Description

  The present invention relates to a photoelectric energy source. More specifically, the present invention relates to the conversion of solar energy into electrical energy using photoelectric (PV) strips.

  The inventor of the present invention has perceived the problem with the use of PV strips to obtain solar energy as how to efficiently direct and concentrate incident light / radiation on the PV strip. Another challenge is how to produce a concentrator with a thin plate of material that can sustain an expected life, such as solar panels, for example 20 years.

  One possible solution was to use a metal concentrator in front of the PV strip. The disadvantage of this solution is that the thickness of the solar panel is greatly increased because the metal concentrator is bulky. Another drawback is that when the metal is exposed, rusting occurs and the reflectivity deteriorates over time.

  Another possible solution that the inventor is concerned with was the use of a thin, transparent polycarbonate layer on top of the PV strip. In such a configuration, many V-shaped grooves are formed in the polycarbonate layer functioning as a prism. The incident light on this prism was directed to the PV strip placed inside the V-shaped groove.

  One possible drawback of such a solution that the inventors are concerned about is the durability and lifetime of such a polycarbonate layer. More specifically, long-term (more than 20 years) translucency (eg, resistance to haze and cracks), geometric suitability (eg, no shrinkage), etc. can be predicted reliably. Can not. Another aspect of the inventor who perceives that it can be durable with respect to lifetime is the gap effect, for example, the gap effect between the PV strip in the PV cell and the wiring.

  Therefore, what is desired is an improved method of manufacturing PV cells or structures and the resulting PV cells or structures.

  The present invention relates to a photoelectric energy source. More specifically, the present invention relates to the conversion of solar energy into electrical energy using photoelectric (PV) strips.

  According to each embodiment of the present invention, a concentrator for incident light is manufactured from a transparent or translucent material (for example, glass or acrylic) and installed near the PV strip. These PV strips are usually interconnected via a series of bus bars. In each embodiment, the material, such as glass, is extruded with a cross section that includes a series of semi-circular regions. In operation, each semi-circular region functions as a solar concentrator that redirects sunlight, eg, parallel light, toward a small region on the surface opposite the semi-circular region.

  In each embodiment, the geometric collection characteristics of the semi-circular region are characterized based on a parallel light source and a photodetector along its length. This characterization is repeated for a plurality of semi-circular regions on the collector plate.

  In each embodiment, the characteristic data may be used as input for PV strip installation work on the sheet of material. For example, such feature data may be used by a user to determine the location of the PV strip for the material. As another example, such feature data may be used by machines or devices that can collect PV strips and accurately position the PV strips relative to a sheet of material. In each embodiment, the installation of PV strip on a sheet of material maximizes the collection of sunlight by the PV strip.

  In each embodiment, the lamination process is performed under predetermined control in order to reduce the space (for example, air gaps) between the wiring gaps in the PV strip, bus bar, or PV assembly. The space is filled with a material such as an adhesive material. More specifically, a laminating process including application of a compression cross section under predetermined management to the PV structure during the above laminating process is performed. In each embodiment, about 1/4 of the air pressure, for example, a compression force of about 25 kPA, is applied to the PV assembly for about 20-30 seconds, eg, 25 seconds. Following this, about a half air pressure, eg, a compression force of about 50 kPA, is applied to the PV assembly for about 30-40 seconds, eg, 35 seconds. In each embodiment, the compression force is applied to the PV structure in a vacuum chamber that is heated sufficiently to melt the adhesive material (eg, at least 120 degrees Celsius, at least 150 degrees Celsius, etc.).

  According to one aspect of the present invention, a method for forming a stacked photoelectric structure is disclosed. One technique includes providing a transparent material having a plurality of concentrating geometries and placing a plurality of photosensitive strips adjacent to the transparent material. The position processing procedure includes disposing a plurality of photosensitive strips adjacent to the first layer of adhesive material, the plurality of photosensitive strips being an existing output of the plurality of concentrating geometries. Depending on the light emission properties, it is positioned with respect to the transparent material, each of the plurality of photoelectric strips being coupled via a plurality of associated bus bars, and a plurality of gap regions between the bus bars of adjacent photoelectric strips. Be placed. As one method, a composite material structure is formed by arranging a robust material layer adjacent to the plurality of photoelectric strips, and after the formation of the structure, the composite photoelectric structure is laminated. Filling the plurality of gap regions with an adhesive material, wherein the adhesive material adheres to the bus bar.

  According to one aspect of the present invention, a stacked photoelectric structure is described comprising: One device includes a transparent material having a plurality of collection geometries. One apparatus includes a first layer of adhesive material disposed adjacent to the transparent material. One system includes a plurality of photosensitive strips disposed adjacent to the first layer of adhesive material, wherein the plurality of photosensitive strips is an existing optical property of the plurality of collection geometries. Accordingly, the plurality of photosensitive strips are coupled to each other via a plurality of bus bars, and a gap region is defined between bus bars of adjacent photoelectric strips. In each embodiment, the thin sheet of transparent material, the plurality of photoelectric strips, and the first layer of adhesive material form a composite photoelectric structure. In each embodiment, a plurality of gap regions between the plurality of photoelectric strips are filled with the adhesive material after the composite photoelectric structure is subjected to a lamination process.

  1A and 1B illustrate aspects according to embodiments of the present invention. More specifically, FIGS. 1A and 1B illustrate an apparatus for determining the light collection characteristics of a thin sheet 100 of material.

  FIG. 1A illustrates one embodiment of a sheet 100 of transparent / translucent material. As can be seen, the thin plate 100 may include a number of light collecting elements 110 in the first direction 120. In one example, there are about 175 light concentrating elements across the thin plate 100, while in other embodiments, the number of light converging elements may vary. In each embodiment, the nominal spacing of the concentrating elements 110 is in the range of about 5.5 to 6 millimeters.

  In each embodiment, the lamella 100 may be manufactured as a lamella of extruded material, and thus the concentrating element may extend in the second direction 130 as shown. In other embodiments, the light collection element may change in the second direction 130.

In general, the light source 140 may provide any type of electromagnetic radiation output, and the photodetector 150 may detect such electromagnetic radiation.

  In each embodiment, the photodetector 150 includes a photodetector such as a CCD or CMOS sensor. In operation, the photodetector 150 may be a two-dimensional sensor and may provide an output that is proportional to the intensity of incident light for each photosensor of the photodetector 150.

  FIG. 1B shows another view of one embodiment of the present invention. In the same figure, the figure which looked at the thin plate 100 from the upper part or the lower part is shown. As shown, the lamina 100 is mounted on a frame assembly 170. In some embodiments, the lamella 100 may be supported only by the frame portion of the frame assembly 170, but in other embodiments, the frame assembly 170 includes a lamella of transparent material such as glass that supports the lamella 100. But you can.

  FIG. 1B illustrates a first moving arm 180 and a second moving arm 190. In each embodiment, the first moving arm 180 may be restrained from moving in the first direction, and the second moving arm 190 may be restrained from moving in the second direction 210. It is contemplated that the first moving arm 180 and the second moving arm 190 may be accurately positioned within the range of the first direction 200 and the second direction 210, respectively.

  In each embodiment of the present invention, the light source 140 is positioned at the intersection of the first moving arm 180 and the second moving arm 190. During operation, the placement of the light source 140 on top of the thin plate 100 is accurately controlled by the positioning of the first moving arm 180 and the second moving arm 190. In each embodiment, the positioning accuracy of the light source 140 is ± 10 microns.

  As shown in FIG. 1A, a similar set of moving arms is usually provided on the opposite side of the thin plate 100. In each embodiment, the photodetector 150 is also positioned at the intersection of these moving arms. In operation, light source 140 and photodetector 150 are typically accurately positioned on the opposite side of lamina 100 as follows.

  In other embodiments of the present invention, other types of positioning mechanisms may be used. For example, a single arm robot arm may be used to accurately position the light source 140, and a single arm robot arm may be used to accurately position the photodetector 150.

  2A-2C illustrate a process flow diagram in accordance with embodiments of the present invention. For convenience, description will be made with reference to the members illustrated in FIGS. 1A and 1B.

  First, as step 300, the thin plate 100 is provided. In each embodiment, the thin plate 100 may be composed of various grades and qualities of glass, plastic, polycarbonate, translucent material, and the like. In each embodiment, the thin plate 100 may include a predetermined number or types of concentrators 110 that are integrally formed within the range of the thin plate 100. In some cases, the thin plate 100 may be formed by an extrusion process, a molding process, a polishing process, or a combination of these processes.

  Next, as step 310, the thin plate 100 is mounted on the supporting frame assembly 170. The sheet 100 is believed to be secured to the frame assembly 170 so that the measurements obtained later are accurate. As described above, the frame assembly 170 may include a thin plate of transparent material such as glass or plastic to support the weight of the thin plate 100.

  In each embodiment of the present invention, as step 320, one or more recombination procedures may be performed to associate the arrangement on the thin plate 100 with the arrangement of the light source 140 and the photodetector 160. For example, the corners of the thin plate 100 may be two-dimensionally arranged with respect to the supporting frame assembly 170. In other embodiments, other types of recombination processes may be performed, such as exposing the light source 140 directly to the photodetector 150 to normalize the amount of light detected in subsequent steps.

  During normal operation, as step 330, light source 140 and photodetector 150 are positioned in place. For example, when the thin plate 100 can be divided into arrangements of the respective arrangements, the light source 140 and the photodetector 150 are arranged in a predetermined arrangement, for example, (0, 0), (14, 19), (32, 32), etc. You may position. Next, when the light source 140 irradiates one of the thin plates 100 including the condensing structure 110 as step 340, the light detector 150 records the luminance of light having the other end of the thin plate 100 as an exit as step 350. .

  In each embodiment of the present invention, the photodetector 150 records the light emitted from each part of the one or more collectors 110. For example, the visible region of the photodetector 150 may record the collection of one or more concentrators 110 as illustrated in FIG. 1B.

  In each embodiment of the present invention, a thin plate of translucent / opaque material, such as EVA, PVB, Surlyn, thermoset, thermoplastic, etc., is placed on the thin plate 100 on the side facing the photodetector 150. May be. In such an embodiment, the light detection of the emitted illumination is facilitated by the thin plate of the material. More specifically, the arrangement / contour and brightness of the outgoing illumination is more apparent to the photodetector 150 due to the diffusion characteristics of the material provided by the manufacturer. In subsequent laminating steps (heating, pressure, aging) described below, the diffusion properties of the sheet material are greatly reduced and the transparency of the sheet material is increased. In each embodiment, the thin plate of the material may be EVA, PVB, Surlyn, a thermosetting material, a thermoplastic material, or the like. In other embodiments, the sheet of material may be a sheepskin material or the like.

  In each embodiment, in step 360, the detected illumination data is associated with the arrangement of the thin plates 100 and stored in the computer memory. In some embodiments, the photodetector 150 may collect and apply one or more illumination data frames. In such an embodiment, the average value of the plurality of illumination frames may be used to reduce the influence of the instantaneous vibration due to the pseudo vibration of the supporting frame assembly, the movement of the light source 140, the photodetector 150, and the like.

  In each embodiment, if illumination data is not collected for all array arrangements, the process may be repeated for further arrangements at step 370.

  Next, in each embodiment of the present invention, in step 380, the cross section of the emitted light of the thin plate 100 is determined using the stored illumination data and the arrangement arrangement data. More specifically, this light section may include the brightness of light about the thin plate 100 and the x and y coordinates.

  In each embodiment of the present invention, based on the cross section of the emitted light, as step 390, an image processing function may be executed to determine positioning data for the placement of the PV strip. For example, one or more centerlines may be determined for the placement of the PV strip by performing a thinning operation on the form, or a contour processing operation may be performed to provide a contour for placement of the PV strip or the like. This positioning data may also be stored in computer memory.

  In some embodiments of the present invention, the width of the light collected by the collector 110 may be less than the narrow width of the PV strip. Thus, in some embodiments, the collected light is centered within the PV strip. This is believed to increase, eg, maximize, the collection of light on any PV strip relative to the emitted light.

  Next, as step 400, the PV strip may be placed on the backing material, such as by using the positioning data by the user. In some embodiments, positioning data, such as center lines, may be printed on the backing material, etc. along the corner positioning lines. Based on such positioning data, a user may manually place a PV strip or PV cell (a group of PV strips, such as a PV assembly, a PV string, a PV module) substantially along the center line. In another embodiment, one or more PV strips or cells are collected and the positioning data is sent to a robotic collection and setting mechanism that places the collected strips or cells in a predetermined arrangement, such as a backing material, vacuum chuck, etc. You may enter. In each embodiment, the installation accuracy may be ± 15 microns. In each embodiment, an adhesive material such as EVA, PVB, Surlyn, a thermosetting material, a thermoplastic material, or the like may be disposed between the PV strip and the backing material.

  In another embodiment of the present invention, for example, disposed in the thin layer of diffusing material, such as EVA, PVB, Surlyn, thermoset, thermoplastic, disposed on the back side of the thin plate 100, eg, opposite the collector 110 May be.

  As step 410, the process may be repeated for the next PV strip or PV cell placement until all desired PV strips or PV cells are installed.

  Subsequently, as step 420, a soldering step is performed to electrically couple and physically constrain one or more PV strips to other PV strips, or one or more PV cells to other PV cells. Also good.

  In each embodiment, as step 430, an adhesive material is placed over the soldered PV strip or PV cell. In some embodiments, a layer of adhesive material such as ethylene vinyl acetate (EVA), polyvinyl butyral (PVB), Surlyn, thermoset, thermoplastic, etc. may be used. Subsequently, in step 440, the thin plate 100 is disposed on the layer of adhesive material. In each embodiment, a predetermined number of positioning marks or the like may be used so that the thin plate 100 is accurately positioned above the PV strip or PV cell. More specifically, the placement of the lamella should be such that the PV strip is positioned in the proper position or location under each concentrator 110.

  In other embodiments, in each of the above steps, if a PV strip is placed over the thin diffusion layer, an additional layer of material such as EVA, PVB, Surlyn, thermoset, thermoplastic, etc. is applied to the PV strip. A backing material may be placed over the additional adhesive layer. Thus, in some embodiments, the composite PV structure is formed by building on top of the sheet 100, while in other embodiments, the composite PV is formed by building on top of the backing material. Is done.

  In each embodiment, as step 450, the material sandwich is bonded / laminated in an oven set to a temperature greater than about 200 degrees Fahrenheit. More specifically, this temperature typically causes the adhesive layer (eg, EVA, PVB, Surlyn, thermoset, thermoplastic, etc.) to melt at (about 120 degrees Celsius, about 150 degrees Celsius, etc.) The temperature is sufficient to bond together with the PV strip or PV cell, backing material, and sheet 100. In some embodiments, in addition to the joining of each material, the adhesive material (eg, EVA, PVB, Surlyn, thermoset, thermoplastic, etc.) can be used as a gap area between previously adjacent PV strips or PV cells. Occupies the area that was. This melting of the adhesive helps to prevent the PV strips from moving laterally relative to each other while at the same time maintaining the alignment of the PV strip with respect to the lamina 100. Also, the adhesive material occupies a region that was previously a gap region between bus bars between PV cells. As described below, the time, temperature, and pressure parameters for the lamination step may be placed under predetermined control for convenience.

  In each embodiment, one or more wires may be drawn before and / or after the joining step to make electrical connections between PV strips or between PV cells. Thus, as step 460, these wires provide electrical energy output from the completed PV panel.

  3A-3C illustrate an embodiment according to embodiments of the present invention. More specifically, FIG. 3A illustrates a cross section 500 of a portion of a transparent sheet 510. As can be seen, a number of concentrators, for example 520 and 525, are illustrated.

  FIG. 3A shows a number of parallel rays 530 from the illumination source that are cast into the air / glass interface and directed towards regions 550 and 560 (regions with collected light). As described above, the sensor collects the arrangement of light collected in regions 550 and 560 on the transparent sheet 510. As shown in this example, a layer of diffusing material 540 may be placed adjacent to sheet 510 to help the sensor collect the placement of regions 550 and 560. As described below, in each embodiment, the layer of the diffusion material 540 may function as an adhesive layer. More specifically, before the lamination process (eg, FIG. 3C), the adhesive layer tends to diffuse incident light, and after the lamination process (eg, FIGS. 3D and 3E), the adhesive layer Tends to fix the PV strip to the glass sheet and tends to be relatively transparent.

  As can be seen in the present embodiment, the concentrators are not usually the same size, shape, or spacing. In fact, it is assumed that the spacing between each collector may vary for a 40 to 500 micron thick sheet. Furthermore, each of the concentrators need not be symmetrical. Therefore, the region where the light is collected may change to be wider when the concentrators are different and adjacent to each other. As can be seen from this example, the region 560 is offset from the center, and the region 560 is wider than the region 550. In other implementations, in fact, many other differences may be apparent.

  As illustrated in FIG. 3B, the width, positioning, etc., of each region of the collected light is not necessarily or normally uniform along the extrusion axis 570 of the glass sheet 510. In this embodiment, the width of each concentrator 580 may change along the extrusion axis 570, and the width of each condensed light region 590 may change along the extrusion axis 570. It can be seen that the light region that has been shifted may deviate from the center.

  In view of the above, it can be seen that due to the large geometrically variable width of the concentrator of the glass sheet 500, proper placement of the PV strip in each collected light region is desirable.

  In the example illustrated in FIG. 3C, the PV strips 600 and 610 are illustrated as being disposed under the regions 550 and 560 of FIG. 3B. In each embodiment, the width of each PV strip is typically 25% wider than the width of each collected light region. In each embodiment, if the light is incident at an angle other than normal to the thin plate 510 (eg, 3 to 5 degrees or more from the normal), the light is believed to be incident on the PV strip. It has been. In the current embodiment, the width of each focused light region is in the range of about 1.8 millimeters to 2.2 millimeters, although other width region ranges are contemplated. For example, as the quality control of the thin plate 510 is enhanced, including the geometric uniformity and geometric accuracy of each concentrator, and the piecemeability of glass, etc., the width of each collected light region is For example, about 0.25 millimeters, 0.5 millimeters, 1 millimeters, etc., which should decrease as the width becomes narrower.

  As illustrated in FIG. 3C, strips 600 and 610 are adjacent to glass sheet 500 and backing layer 630 via adhesive layers 620 and 625. As can be seen, in each embodiment, the first adhesive layer 620 may be disposed between each PV strip (600 and 610) and the backing layer 630, and the second adhesive layer 625 includes It may be placed between the PV strips (600 and 610) and the glass sheet 625. In addition, gap regions, such as region 640, exist between adjacent bus bars 605 and 615 and between adjacent PV strips (600 and 610). In some embodiments, the height between adjacent bus bars is typically less than 200 microns.

  In FIG. 3D, the structure illustrated in FIG. 3C is subjected to a precisely managed stacking process. In the case of an adhesive layer formed from a layer of a material such as EVA, PVB, Surlyn, thermosetting material, or thermoplastic material, the first adhesive layer 620 and the second adhesive layer 625 melt and re-flow out. As can be seen in FIG. 3D, the first adhesive layer 620 and the second adhesive layer 625 may be mixed together to form a single layer, as illustrated by the adhesive layer 650. In each such embodiment, the gap between the PV strip and the bus bar, such as the gap region 640 prior to the lamination process, is filled with an adhesive material, such as EVA, after the lamination process. In each embodiment, the adhesive layer adheres to each PV strip and / or each bus bar. As a result, the PV strips 600 and 610 are not simply secured to the glass sheet 500 and the backing layer 630, but are secured laterally to each other by the re-flowed EVA material. Further, the separation state between the bus bars 605 and 615 is maintained as before. In each embodiment, the adhesive material functions as a barrier that reduces soldering shorts between adjacent PV strips and / or between adjacent bus bars, for example, as a result of a user pressing on each bus bar connecting each PV strip. To do. Furthermore, the adhesive material functions as a barrier against steam, rust, contamination, and the like. In other embodiments of the present invention, a single adhesive layer may be used, as illustrated in FIG. 3E.

  In each embodiment of the invention, the lamination process includes a precisely controlled time, temperature, and / or physical compression variable cross section. In one embodiment, the pressing force pressed against the material stack is in the range of about 0.2 to 0.6 atmospheres. In each embodiment, as a cross-section of the lamination pressure, the structure illustrated in FIG. 3C is exposed to a pressing force of about 25 kPA (about 1/4 atm) for about 25 seconds, and then about 50 kPA (about 1) for about 50 seconds. / 2 atm). During this period, the EVA material or the like is heated to a melting point, for example, about 120 degrees Celsius or more, about 150 degrees Celsius or more, depending on the melting point of a specific type of adhesive material.

  Experimentally, the inventor has shown that when the lamination process is performed under a pressure of about 1 atmosphere, as the adhesive material, e.g. EVA, melts and reflows, the gap region is adjacent as described above. It remains between the PV strips and between the bus bars between adjacent PV strips. In other embodiments of the present invention, other time, temperature, and compression force combinations that provide the advantages described above may be set without undue experimentation by those skilled in the art.

  In another embodiment of the present invention, when other adhesive materials such as PVB, Surlyn, thermosetting material, and thermoplastic material are used, the characteristics such as time, temperature, pressure, etc. The user may similarly monitor in such a manner as to perform the same function as the material. More specifically, it is desirable that the adhesive material fills the void area between the PV strips and provides the protective and preventive properties described above.

Since the material has photosensitivity, the region where the sunlight is collected after a certain time may be brighter or darker than other regions under the glass sheet. In such embodiments, the material can be used as a visible template for PV strip or cell installation. More specifically, the user can easily install the PV strip in an area where sunlight is collected. Once all the PV strips are installed, the photosensitive material may be removed or used as part of the lining described above. As can be seen from such an embodiment, a computer, a digital image sensor, an accurate xy table, and the like are not necessary for carrying out the embodiment of the present invention.

More specifically, the laser misalignment sensor may be used according to steps 300-380 in FIGS. 2A and 2B. In each such embodiment, the optical cross section measured and determined in step 380 is determined as described above. Further, the surface of a thin plate made of a transparent material such as glass may be measured geometrically using a laser displacement sensor. This is believed to determine the accurately measured geometric surface of the transparent material. In some embodiments of the present invention, a KeyenceLK CCD laser misalignment sensor or the like can be used.

  In such an embodiment, the measured geometric model of the transparent material and the determined light section are then associated with each other. In each embodiment, a predetermined number of conventional software algorithms can be used to create a computer model of the transparent material. This computer model, as an input, associates a description of the geometric surface and outputs a predicted outgoing light arrangement. In each embodiment, a number of transparent materials may be subjected to steps 300 to 380 to determine a number of optical cross sections, or the transparent material may be subjected to laser measurement to determine a number of geometric surfaces after the measurement. Also good. In each embodiment, the computer model may be based on these multiple data samples.

  Subsequently, in each embodiment of the present invention, a new transparent material may be provided. This new transparent material is subjected to a laser measurement to determine the geometric surface after the measurement. Based on the measured geometric surface and the determined computer model, the computer system can then predict the placement of illumination emitted from the new transparent material. In each embodiment, steps 390 through 460 may be performed using the predicted exit illumination arrangement.

  In other embodiments of the invention, other types of measurement devices such as physical probes may be used in addition to lasers.

  In other embodiments of the present invention, each PV strip may be placed on top of an EVA laser or the like directly below the bottom of the glass concentrator. These materials may be subjected to heat treatment as described above. Thus, in each such embodiment, a robust backing material is not required. In still another embodiment, the light source may be a light source such as an area light source, a line light source, or a point light source. The light may be a two-dimensional CCD array, line array, or the like.
