Abstract
The utility model discloses a novel photovoltaic assembly which successively a front toughed glass substrate, a polymer packaging layer and a back toughened glass substrate from top to bottom, wherein the front toughened glass substrate can absorb or reflect infrared and ultraviolet light, the polymer packaging layer is internally provided with crystalline silica cells, the inner surface of the front toughed glass substrate is a textured surface, and the inner surface of the back toughened glass substrate includes a radiating film layer. An aluminum alloy frame is mounted in the periphery of a laminated layer which is composed of the substrates and packaging layer. The novel photovoltaic assembly is reasonable in structure; during work of the photovoltaic assembly, infrared or ultraviolet light in solar spectrum is absorbed or reflected by the front toughened glass substrate, so that infrared or ultraviolet light entering the packaging layer is reduced, the temperature of the assembly is reduced, and the output power and service life of the assembly are improved; and the radiating film layer at the air side of the back glass substrate is conducive to heat radiation of the assembly, the temperature of the assembly is further reduced, and the accumulated power generating capacity of the assembly is increased.
Description
Technical field
The utility model relates to a kind of photovoltaic module.
Background technology
Photovoltaic module is the core parts of photovoltaic generation application.According to inventor, understand, the front glass sheet of two glass photovoltaic modulies of at present domestic and international suitability for industrialized production does not have the good characteristic of absorption or reflects infrared light or ultraviolet light, can cause like this temperature of component internal to raise, thereby cause the power output of assembly and useful life to decline, and back-panel glass is transparent or semitransparent, can make like this light directly from backboard transmission, go out, make battery, cannot be from the reverberation that absorbs back-panel glass dividing, thereby affect output power of photovoltaic module, simultaneously, because the inner surface of the back-panel glass of conventional two glass photovoltaic modulies does not have heat dissipating layer structure, thereby cannot effectively the temperature of assembly be distributed, cause the temperature of assembly effectively not reduce, thereby affect the heat dispersion of assembly, and then the power output of the two glass photovoltaic modulies of impact, simultaneously, the thickness of glass of conventional two glass assemblies is larger, weight is large, be difficult for carrying, what use is conventional plastic junction box, easily cause terminal box internal temperature higher, the useful life of infringement inner member, and then affect useful life of assembly.
Summary of the invention
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and can effectively reduce component internal temperature, improves the novel photovoltaic module of assembly reflectivity.
Technical solution of the present utility model is:
A novel photovoltaic module, is characterized in that: the header board toughened glass matrix, polymer encapsulated layer, the backboard toughened glass matrix that comprise successively from top to bottom energy absorption or reflective infrared and ultraviolet light; In polymer encapsulated layer, be provided with crystal silicon cell, header board toughened glass matrix inner surface has texturing matte, backboard toughened glass matrix inner surface heat radiation rete; The lamination periphery of above-mentioned each layer of composition is equipped with aluminum alloy frame.
The thickness of header board toughened glass matrix is 2mm; The thickness of backboard toughened glass matrix is 2mm.
Described polymer encapsulated layer can absorb for having UV, replaces the polymer encapsulating material of the functions such as coloured backboard, ceramic plated layer, coloured glass.
Described terminal box is the terminal box of metallic wiring box or other suitable materials.
The utility model is rational in infrastructure, photovoltaic module is in when work, and the infrared light in solar spectrum or ultraviolet light are absorbed or reflect header board is on glass, thereby reduces the amount that infrared light or ultraviolet light incide encapsulated layer, reduce the temperature of assembly, the power output of lifting subassembly and useful life; The heat radiation rete of back-panel glass air side is conducive to the heat radiation of assembly, reduces the temperature of assembly, improves the accumulated generation amount of assembly.
When polymer encapsulated layer is used polymer material, reflection ray forms diffuse reflection, finally makes reflection ray project on solar cell uniformly, thus temperature and the in uniform light of the whole solar cell of balance photovoltaic module, the power output of lifting photovoltaic module.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the structural representation of an embodiment of the utility model.
