Description
Technical field
The utility model belongs to photoelectricity and building materials field, specifically is a kind of double side photovoltaic battery wall component, is applicable on the buildings such as large glass curtain buildings, parking lot, public place of entertainment.
Background technology
Curtain wall component is a kind of building material that integrates generating, sound insulation, heat insulation, safety, decoration functions, has demonstrated fully the intellectuality and the human features of building.
Curtain wall component promptly is posted on glassly with special resins with solar cell is sticking, is embedded between two sheet glass, luminous energy can be changed into electric energy by battery.Except that this major function of generating, functions, particularly solar cell power generation such as that photoelectric curtain wall also has is significantly heat insulation, sound insulation, safety, decoration can not discharged carbon dioxide or be produced the gas harmful to greenhouse effect, noiselessness yet, be a kind of net energy source, good compatibility arranged with environment.But because of the price comparison costliness, now roof and the exterior walls that are used for landmark building of photoelectric curtain wall more.
At present, traditional curtain wall component is being selected aspect the battery sheet, usefulness be single face monocrystalline solar cells or polycrystalline solar cell etc., the shortcoming of single face solar cell is, can only use single face, collects sunshine, and transform light energy is become electric energy; But because of its back side be with glass as backboard, glass has light transmission, and its, this single face battery can only generate electricity with one side, to its select back veneer material with, this is undoubtedly a kind of waste.
Summary of the invention
Problem at above-mentioned makes full use of resource, and the utility model provides a kind of double side photovoltaic battery wall component that utilizes the double-sided solar battery sheet.
Double side photovoltaic battery wall component described in the utility model comprises upper strata glass, bottom glass and middle photovoltaic cell component, described photovoltaic cell component comprises at least one group of double-sided solar battery sheet, every group of double-sided solar battery sheet comprises a slice double-sided solar battery sheet at least, wherein connect with interconnector between each double-sided solar battery sheet, be connected to junction box with busbar between every group of double-sided solar battery sheet; Be sealing adhesive with EVA between upper strata glass, bottom glass and the double-sided solar electromagnetic plate, EVA is the copolymer of ethene-vinyl acetate, makes glass, EVA, complete the bonding together of battery, and inside is vacuumized, and has guaranteed the life-span of assembly.
Also be connected with bypass diode between described every group of double-sided solar battery sheet, solved the assembly hot spot effect.
Described junction box is fixed with casting glue, guarantees water proofing property.
Preferably, we are set as follows: photovoltaic cell component is set to 6 groups, every group and comprises 10 double-sided solar battery sheets, promptly has 60 battery sheets.And described double-sided solar battery sheet is two-sided monocrystaline silicon solar cell sheet.And upper strata glass is set to ultrawhite tempered glass, because ultrawhite tempered glass, the light transmittance height simultaneously, can stop a part of infrared rays and ultraviolet irradiation, can reduce ultraviolet radiation and keep interior temperature, and lower floor then is a simple glass.
The utility model has thoroughly solved the purposes problem of two-sided battery, more fully two-sided battery is used in photoelectric field.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.Be converted to electric energy with sunshine daytime under irradiation of sunlight, and with electrical power storage in battery, use for load; In evening, the light in the solar cell absorption chamber of reverse side is converted to electric energy, and is stored in the battery, uses for load.Owing to be to adopt two-sided battery sheet, increased the power of assembly greatly.
That this curtain wall component not only has is heat insulation, sound insulation, functional characteristics such as attractive in appearance, can generate electricity simultaneously, and be two-sided generating; Compare with conventional curtain wall, further reduced the temperature in room aspect heat insulation, more fully two-sided battery is used in the photovoltaic power generation.

Wherein, 1. be upper strata glass, 2 is lower floor's glass, and 3 is EVA, and 4 is busbar, and 5 is interconnector, and 6 is the battery sheet, and 7 is junction box, and 8 is diode.
The specific embodiment
Further explain, illustrate the technical program with non-limiting embodiment below.
A kind of double side photovoltaic battery wall component comprises upper strata glass, bottom glass and middle photovoltaic cell component, described photovoltaic cell component comprises 6 groups of double-sided solar battery sheets, every group of double-sided solar battery sheet comprises 10 double-sided solar battery sheets, wherein connect with interconnector between each double-sided solar battery sheet, be connected to junction box with busbar between every group of double-sided solar battery sheet; Be sealing adhesive with EVA between upper strata glass, bottom glass and the double-sided solar electromagnetic plate, EVA is the copolymer of ethene-vinyl acetate, makes glass, EVA, complete the bonding together of battery, and inside is vacuumized, and has guaranteed the life-span of assembly.
Also be connected with bypass diode between described every group of double-sided solar battery sheet, solved the assembly hot spot effect.
Described junction box is fixed with casting glue, guarantees water proofing property.
And upper strata glass is set to ultrawhite tempered glass, because ultrawhite tempered glass, the light transmittance height simultaneously, can stop a part of infrared rays and ultraviolet irradiation, can reduce ultraviolet radiation and keep interior temperature, and lower floor then is a simple glass.
The battery sheet can be selected the two-sided monocrystaline silicon solar cell sheet of 15.0% conversion efficiency, and employing is 60 a battery sheet, and the power of the assembly that encapsulates is, (at air quality AM1.5, temperature is at 25 ℃, light intensity 1000W/m
2) front is 127W, reverse side is 70W, overall power is 197W.And common single face battery curtain wall assembly with the battery sheet of this conversion efficiency, can only be made 130W.All, we in contrast to this, power has increased 95W.
When using, owing to only can use one side to produce electric energy, promptly when selecting positive the use, reverse side is disabled; When selecting for use reverse side to use, the front is disabled.So can select following use: daytime is bright and clear, it is many to produce electric energy, selects positive the use; Evening is indoor light, selects reverse side to use.
