Abstract
The utility model discloses a two-sided battery assembly, which is made of a transparent triphenyltin (TPT) material and is applicable to the photoelectricty and building material field. The transparent TPT is adopted to replace the traditional rear panel glass by the assembly; the lamination structure of the glass plus ethylene-vinyl acetate (EVA) plus battery plates plus EVA plus TPT is formed; two-sided solar battery plates are connected through interconnectors; groups of two-sided solar battery plates are connected with a junction box through bus bars and outgoing lines; the assembly is laminated and then an aluminum frame is installed on the laminated assembly. The two-sided battery assembly is convenient to process, is attractive and can generate electricity from two sides; compared with the traditional double-glass assembly, the processing process is further simplified, the assembly weight is reduced, and a two-sided battery can be applied to the photoelectricty and building material field more fully.
Description
Technical field
The invention belongs to the solar module technical field, be specifically related to the transparent again battery component of a kind of two-sided generating, be applicable to that large glass curtain buildings, parking lot, highway soundproof wall etc. are architectural, also be applicable to generating environment such as desert and snowfield.
Background technology
Double-sided solar battery is the positive and negative of battery sheet, under the irradiation of light, can produce corresponding power, thus the power of indirect increase photovoltaic module, the corresponding conversion efficiency of raising monolithic battery sheet.When two-sided battery component is installed on building, under irradiation of sunlight, can utilize daytime the front of assembly that sunlight is converted to electric energy; In evening, the light in the solar cell absorption chamber of reverse side is converted to electric energy.So just increased the power of assembly greatly.
The general upper strata of existing solar photovoltaic assembly is high transparent glass, lower floor is lighttight TPT(polyvinyl fluoride composite membrane) backboard, the centre is EVA film and solar battery sheet, the photovoltaic module of this standard is opaque, be not suitable for the use of two-sided battery, also do not reach not only generating electricity but also transparent effect of BIPV requirement.Therefore traditionally for reach the transparent daylighting of assembly, can the two sides generating effect, often assembly adopts layer glass to carry out lamination.As Chinese patent application number be: among the CN200810138159.4, a kind of double side photovoltaic battery wall component and preparation method thereof is disclosed, the photovoltaic module of this invention comprises following structure: layer glass before and after photovoltaic module adopts, wherein top layer is a solar energy ultra-white glass, the intermediate layer is two-layer EVA glue, accompanies two-sided crystalline silicon solar cell piece between the two-layer EVA glue.
The photovoltaic module of the two glass structures of this employing has solved the application problem of printing opacity and two-sided battery, but have the following disadvantages: existing laminating machine process conditions when making two glass assembly are complicated, because glass is hot non-conductor, adopt the layer glass lamination, the glass gross thickness is thicker, EVA glue is vacuumizing, is causing easily when thawing, lamination bad phenomenon such as the crushing of battery sheet, the displacement of battery sheet, double glazing dislocation, bubble, finished product rate to cannot say for sure card.Simultaneously, double glazing assembly own wt is heavier, when the application of sunshade, daylighting top and the daylighting curtain wall of some low-rise buildings, increases building cost, does not have advantage.
Summary of the invention
At the above-mentioned technical problem that exists in the prior art,, the invention provides a kind of two-sided battery component in order to simplify molding technological condition, make full use of resource, save the goal of the invention of building cost.
The technical solution adopted for the present invention to solve the technical problems is:
Two-sided battery component, adopt transparent TPT material to replace traditional back-panel glass, described assembly is followed successively by the laminated construction of glass, EVA glued membrane, two-sided battery sheet, EVA glued membrane and TPT from top to bottom, connect with interconnector between each double-sided solar battery sheet, be connected to terminal box with busbar and lead-out wire between every group of double-sided solar battery sheet, the aluminium frame is installed around the described assembly.
Wherein, be connected with bypass diode between every group of double-sided solar battery sheet, bypass diode and terminal box one are reinstated the casting glue sealing, and are fixed in the centre position of assembly topmost with transparent silica gel.
The present invention adopts transparent TPT material, has not only solved the purposes problem of two-sided battery, and has simplified the molding technological condition of two-sided battery component, and the assembly of formation has advantages such as attractive in appearance, that moulding process is easy; Compare with traditional double glass assembly, alleviated assembly weight, further reduced cost, can more fully two-sided battery be used in photoelectricity and the building materials field.
Description of drawings
Fig. 1 is the structural representation of the two-sided battery component of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done explanation in further detail.
Two-sided battery component by transparent TPT material, comprise upper strata glass, bottom transparent back panel and middle double-sided solar battery sheet 1, described two-sided battery component comprises 6 groups of double-sided solar battery sheets, every group of double-sided solar battery sheet comprises 12 double-sided solar battery sheets 1, wherein connect with interconnector 3 between each double-sided solar battery sheet 1, be connected to terminal box 6 with busbar 4 and lead-out wire 7 between every group of double-sided solar battery sheet; With EVA laminating seal bonding, aluminium frame 2 was made on assembly refilled after lamination is finished between upper strata glass, bottom transparent back panel and the double-sided solar battery sheet 1; Aluminium frame 2 is doorframe, a window frame industrial aluminum profile commonly used, and terminal box cable 5 is connected with terminal box 6.
Be connected with bypass diode between every group of double-sided solar battery sheet, can effectively prevent the hot spot effect of assembly.Terminal box 6 adopts transparent silica gel to fix, and uses the casting glue sealing, has guaranteed the water proofing property of assembly.Terminal box adopts special little photovoltaic junction box, when guaranteeing the electrical component performance, can also guarantee the attractive in appearance of assembly, has effectively solved the problem that conventional photovoltaic junction box blocks cell backside.
The photovoltaic cell component upper strata glass of present embodiment is set to ultrawhite toughened glass, and is provided with 6 groups, every group and comprises 12 double-sided solar battery sheets 1, totally 72 battery sheets.Double-sided solar battery sheet 1 has been selected positive 17.2% conversion efficiency, and the two-sided monocrystaline silicon solar cell sheet of the back side 12.8% conversion efficiency adopts 72 battery sheets, and the component power that encapsulates is, (at air quality AM1.5, temperature is at 25 ℃, light intensity 1000W/m
2) front is 176W, the back side is 140W, overall power is 316W.And common monocrystalline single face battery component with the battery sheet of this conversion efficiency, can only reach 185W.So compare with the single face assembly, the two-sided power of battery of the present invention has increased 131W.
