Abstract
The invention provides a novel photovoltaic module structure. The novel photovoltaic module structure comprises glass and a back plate, wherein a battery plate, and a bus bar and a solder strip connected with the battery plate are arranged between the glass and the back plate; an EVA adhesive film with high light transmission is laid between the glass and the battery plate; and an ageing-resistant EVA adhesive film is laid between the battery plate and the back plate. The novel photovoltaic module structure has the advantages of having high light transmission and ageing resistance, improving the photoelectric transformation efficiency, prolonging the service life and lowering the module cost.
Description
Technical field
The present invention relates to a kind of photovoltaic module structure.
Background technology
Solar energy power generating is a kind of regenerative resource of cleaning, and photovoltaic electrification component is made up of the backboard of glass, electrooptical device such as the crystal silicon battery sheet of preposition protection, the ethylene vinyl acetate polymer (EVA) that plays encapsulation effect, rearmounted protection usually.
For making EVA reach the service life similar to the assembly other materials, the assembly that uses all adopts the EVA glued membrane that possesses the ultraviolet cut-on function as encapsulating material at present, initial power with the reduction assembly is a cost, strengthens encapsulating material EVA anti-xanthochromia characteristic when outdoor application.Publication number is that the patent specification of CN 101353558A discloses the EVA glued membrane that a kind of not ultraviolet cut-on but possesses anti-xanthochromia, the shortcoming ultraviolet light that is assembly when using this class EVA can see through the inner surface that glass and EVA finally reach backboard, this just requires backboard to have anti-preferably ultraviolet characteristic, otherwise can cause the backboard xanthochromia and influence the assembly outward appearance.
Summary of the invention
The present invention will solve the prior art existence can not possess high transmission rate and ageing-resistant problem simultaneously, provides a kind of and has not only possessed high transmission rate but also possess ageing-resistant novel photovoltaic module structure.
Technical scheme of the present invention:
Novel photovoltaic module structure, comprise glass and backboard, the busbar and the welding that between described glass and backboard, are provided with the battery sheet and connect the battery sheet, it is characterized in that: be equipped with high printing opacity EVA glued membrane between described glass and the battery sheet, be equipped with ageing-resistant EVA glued membrane between described battery sheet and the backboard.
Further, described high printing opacity EVA glued membrane reaches the average transmittance that possesses more than 90% by adding auxiliary agents such as crosslinking agent, antioxidant, light aging resisting agent, silane coupler.
Further, described ageing-resistant EVA glued membrane reaches ultraviolet absorption effect by adding the reflectivity of increases such as talcum powder, titanium dioxide, hollow glass microballoon, calcium carbonate powder, silicate powder, pigment or toner to ultraviolet light by adding salicylic acid based compound, benzo oxazinyl compound, benzophenone based compound and BTA based compound class ultraviolet absorber.
High printing opacity EVA glued membrane does not possess tangible absorption feature to the ultraviolet light between 300nm～380nm, and the light mean transmissivity is more than 90%; Possessing non-discoloring ability under the ultraviolet irradiation for a long time.
Ageing-resistant EVA glued membrane possesses tangible absorption or reflectance signature to the ultraviolet light between 300nm～350nm, and the ultraviolet light mean transmissivity is below 50%.
At the high printing opacity EVA glued membrane of the positive use of battery sheet, can improve the solar flux that projects battery sheet surface, thereby improve the photoelectric conversion efficiency of solar photovoltaic assembly.
Use ageing-resistant EVA glued membrane at the cell back face, can increase the ageing-resistant performance of assembly, the protection back veneer material is avoided solar light irradiation, prolongs backboard useful life, perhaps reduces the performance requirement of solar module to backboard, reduces the assembly cost.
Beneficial effect of the present invention: have high light transmittance and ageing-resistant performance, improved photoelectric conversion efficiency, increase the service life, the assembly cost is low.
