Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

Furthermore, the drawings are merely schematic illustrations of embodiments of the disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted.

A crystalline silicon photovoltaic module is provided in this example embodiment. Referring to fig. 1 to 3, the crystalline silicon photovoltaic module includes a cell package 100, a wire 200, and a flexible frame strip 300. The cell package 100 is a package of a crystalline silicon cell 110, and the cell package 100 may or may not include a package frame, which is not limited by the present disclosure.

The lead 200 includes a plurality of positive leads 210 and negative leads 220, one ends of the positive leads 210 and the negative leads 220 are located inside the battery piece package 100 and are respectively connected with the positive and negative electrodes of the battery piece 110, the other ends of the positive leads 210 and the negative leads 220 are led out from the side end faces of the battery piece package, wherein one positive lead 210 is led out from each adjacent three side end faces, and one negative lead 220 is correspondingly led out from the side end face opposite to each led-out positive lead 210. Specifically, as shown in fig. 2, one positive electrode lead 210 is led out from a side end face a, one negative electrode lead 220 is led out from a side end face C opposite to the side end face a, and one positive electrode lead 210 and one negative electrode lead 220 are led out from a side end face B and a side end face D opposite to the side end face B, respectively, of four side end faces of the battery piece package 100. In this way, most of the lead 200 except a small part of the end part is packaged inside the battery piece package 100, and the service life of the lead 200 is prolonged.

The flexible frame strip 300 is fixed to, for example, bonded to, four side end surfaces of the cell sheet package 100. The surface of the flexible frame strip 300 is provided with a magnetic-type electrode 400, and the magnetic-type electrode 400 is connected with the led-out positive electrode lead 210 or negative electrode lead 220. The surface of the flexible frame strip 300 refers to a surface of the flexible frame strip 300 perpendicular to the side end surface after being fixed to the battery package 100.

Specifically, the number of the magnetic electrodes 400 on each flexible frame strip 300 is equal to the number of the wires 200 led out from each side end surface. For example, referring to fig. 2, a lead 200 is led out from each of the side end surfaces a and C, and correspondingly, a magnetic-attraction electrode 400 is respectively disposed on the flexible frame strip 300 connected to the two side end surfaces; two wires 200 are led out from the side end surface B and the side end surface D, and two magnetic electrodes 400 are also disposed on the flexible frame strip 300 connected to the two side end surfaces.

In a specific example, when the magnetic-type electrode 400 is connected to the led-out positive electrode lead 210 or negative electrode lead 220, a gap may be left in advance at a position corresponding to the flexible frame strip 300, and only the end of the positive electrode lead 210 or negative electrode lead 220 needs to be inserted into the gap and connected to the magnetic-type electrode 400. Magnetic-type electrode 400 can be formed by the adhesion of magnetic attraction pieces and electrodes, and in order to make each flexible frame strip 300 more firm, the area of magnetic attraction pieces can be relatively larger, and this disclosure does not limit this.

When a plurality of crystalline silicon photovoltaic modules need to be spliced, the flexible frame strips 300 of each crystalline silicon photovoltaic module can be connected in a magnetic attraction mode in a series or parallel mode according to requirements. On the one hand, the flexible frame strip 300 has certain elasticity and softness, and the position where the flexible frame strip 300 is located can be bent after the splicing of a plurality of crystalline silicon photovoltaic modules, so that the spliced large-area photovoltaic module can be suitable for more complex scenes, for example, the spliced large-area photovoltaic module is placed on the ground with fluctuation or randomly placed on the surface of an appliance, and is not limited to be placed only in a flat place. On the other hand, the mode of magnetism between the flexible frame strip 300 for photovoltaic module concatenation is more laborsaving, has avoided appearing damaging the phenomenon of subassembly because of the extrusion block in the concatenation process.

When the splicing method is actually used, a user can select a serial-parallel splicing mode according to the total voltage or the total current which is finally required to be output.

When the crystalline silicon photovoltaic modules are connected in series, the flexible frame strip on the side end face A of one crystalline silicon photovoltaic module can be connected with the flexible frame strip on the side end face C of the adjacent crystalline silicon photovoltaic module, and the rest is analogized, so that the anode and the cathode of the plurality of crystalline silicon photovoltaic modules are connected in series. When the number of the photovoltaic modules is large and all the photovoltaic modules are strung into one row and are too long, the photovoltaic modules can be divided into a plurality of rows, the photovoltaic modules at the tail ends between the adjacent rows are connected through the serial connection strips, and finally, the positive and negative electrode output ends of the whole serial connection crystalline silicon photovoltaic module are respectively led out through the positive and negative electrode lead strips.

When the crystalline silicon photovoltaic modules are connected in parallel, the flexible frame strip on the side end face B of one crystalline silicon photovoltaic module can be connected with the flexible frame strip on the side end face D of the adjacent crystalline silicon photovoltaic module, the positive and negative magnetic attraction electrodes on the two flexible frame strips are correspondingly butted, the rest is analogized, the parallel connection of the plurality of crystalline silicon photovoltaic modules is realized, and finally, the positive and negative output ends of the whole parallel crystalline silicon photovoltaic module are respectively led out by the positive and negative lead strips.

In one embodiment, the flexible frame strip 300 includes a first flexible frame strip 310 and a second flexible frame strip 320, a groove 311 is disposed on a surface of the first flexible frame strip 310 perpendicular to a side end surface of the battery sheet package 100, a protrusion 321 is disposed on a surface of the second flexible frame strip 320 perpendicular to the side end surface of the battery sheet package 100, the groove 311 matches with the protrusion 321, the first flexible frame strip 310 and the second flexible frame strip 320 are respectively fixed on opposite side end surfaces of the battery sheet package 100, and a concave direction of the groove 311 is opposite to a convex direction of the protrusion 321. When a plurality of crystal silicon photovoltaic modules are spliced, the convex columns 321 are just embedded into the grooves 311 in the splicing process, which is equivalent to the splicing between the first flexible frame strips 310 and the second flexible frame strips 320, so that the connection between the flexible frame strips is tighter and firmer.

Specifically, referring to fig. 3, the first flexible frame strip 310 is fixed on a side end surface D of the battery cell package 100, and the second flexible frame strip 320 is fixed on a side end surface B of the battery cell package 100. In this example, the groove 311 on the first flexible frame strip 310 is a lower groove, and the protrusion 321 on the second flexible frame strip 320 is an upward protrusion, but the disclosure is not limited thereto, in other examples, the groove 311 on the first flexible frame strip 310 may also be an upper groove, and correspondingly, the protrusion 321 on the second flexible frame strip 320 is a downward protrusion, that is, only when the groove 311 and the protrusion 321 are engaged with each other during the splicing process. Similarly, the first flexible frame strip 310 and the second flexible frame strip 320 fixed on the side end surface a and the side end surface B of the battery piece package 100 are also configured as such, and are not described herein again.

In one embodiment, as shown in fig. 3, the magnetically attractable electrode 400 is disposed in the groove 311 of the first flexible frame strip 310 and on the protrusion 321 of the second flexible frame strip 320. In the splicing process, when the convex pillar 321 is embedded into the groove 311, the magnetic-type electrode 400 can be better connected.

For example, the groove 311 may extend along the length direction of the first flexible frame strip 310, and correspondingly, the protrusion 321 also extends along the length direction of the second flexible frame strip 320, as long as the relative positions of the groove 311 and the protrusion 321 are ensured to correspond, which is the extending form in fig. 3. In another example, the groove 311 may also extend along the width direction of the first flexible frame strip 310, and the protrusion 321 extends along the width direction of the second flexible frame strip 320.

In one embodiment, the magnetically-attracted electrode 400 includes a magnetically-attracted electrode contact 410 and a magnetically-attracted electrode contact 420, and the magnetically-attracted electrode contact 410 and the magnetically-attracted electrode contact 420 are respectively located on the flexible frame strips 300 fixed on the opposite side end surfaces of the cell package member 100. For example, the magnetically attracted electrode contact 410 is disposed on the flexible frame strip 300 on the side end surface a, and the magnetically attracted electrode contact 420 is disposed on the flexible frame strip 300 on the side end surface C opposite to the magnetically attracted electrode contact 410, or vice versa. Similarly, the magnetic-type electrodes 400 on the flexible frame strips 300 on the side end surfaces B and D are also configured in this way.

Further, the magnetically attracted electrode contact 410 is a magnetically attracted elastic electrode contact. When the flexible frame strip 300 is bent, the magnetic attraction type elastic electrode contact can be ensured to be in contact with the magnetic attraction type electrode contact piece constantly, and good contact between the electrodes is ensured.

In one embodiment, the battery sheet package 100 includes a glass, a silicon-silicon battery sheet, and a back sheet, which are packaged together by an adhesive film, which may be EVA (Polyethylene vinyl acetate) or POE (polyolefin elastomer).

To sum up, the utility model provides a crystal silicon photovoltaic module, portable, and the large tracts of land photovoltaic module after the concatenation is applicable in more complicated scenes, no longer limits to and only places in level and smooth place. In addition, the mode of magnetism between the flexible frame strip for photovoltaic module concatenation is more laborsaving, has avoided appearing damaging the phenomenon of subassembly because of the extrusion block in the concatenation process.
