Therefore, the provided solar cell assembly has good insulation and sealing properties and the electricity leakage can be prevented and the water vapor can be stopped from entering the inside of the cell core plate, thereby ensuring the security of the cell assembly and prolonging the service life of the cell assembly.
Description
Technical field
The utility model relates to a kind of no frame Thinfilm solar cell assembly for BIPV, belongs to the solar photovoltaic technology field.
Background technology
No frame Thinfilm solar cell assembly is widely used in BIPV, yet technical problems such as the fail safe of photovoltaic module and edge current leakage thereof receive much concern always.
Adopt the structure of the no frame thin-film solar cells of glass packaging to be: preceding glass sheet+glued membrane+hull cell central layer+glued membrane+back-panel glass; battery component is by PVB or the high pressure sealing of EVA glued membrane hot melt; but in phenomenons such as not pressing tightly, the glued membrane adhesion strength is not enough can appear in edge usually; and in the long-term process of using of battery component; moisture can see through PVB or the EVA glued membrane penetrates into inside battery, influences the electrical property of battery.In order to prevent that steam from entering battery component, at edge's coating silica gel of battery component frame is installed.Chinese patent ZL 200920286929.X " a kind of solar module that contains butyl sealant " and ZL 201010268702.X " a kind of boundless frame solar battery component and method for packing " disclose a kind of in the hull cell central layer outside, the technical scheme that back-panel glass edge inboard coating butyl rubber seals, because the sealing of butyl rubber is better than EVA and PVB glued membrane, can effectively alleviate the electric leakage problem at battery component edge, but the butyl rubber sealed width is subjected to the restriction of size of components, can not make very wide, battery component still can infiltrate inside battery at the long-time back steam that uses, and battery component is through behind the lamination, butyl rubber width in it differs, and influences attractive in appearance.
Summary of the invention
In order to prevent that steam from entering battery component, better solve the sealing problem of battery component, the utility model has designed a kind of no frame Thinfilm solar cell assembly, the peripheral membrane removal of solar battery core board is handled, be packaged as a whole by glued membrane, header board and backboard, apply the composite film that is formed by stacking in proper order by insulation paint film, butyl rubber and glued membrane between the shady face of solar battery core board and the backboard.
Insulation paint film, butyl rubber and glued membrane in the composite film successively are coated on the shady face of solar battery core board successively.
Insulation paint film in the composite film and butyl rubber all cover the diaphragm area that has of solar battery core board, and the size of insulation paint film and butyl rubber is all less than the substrate of solar battery core board.
Between glass sheet and the back-panel glass, glued membrane coated solar battery core board, and the size of glued membrane is less than preceding glass sheet and back-panel glass before solar battery core board was encapsulated in by glued membrane.
Gap between preceding glass sheet and the back-panel glass is filled with butyl rubber.
Insulation paint film in the composite film mainly is made of organic siliconresin, superfine SiO 2 particle and the colouring agent of modification.
The beneficial effects of the utility model are: the shady face of solar battery core board is provided with composite film; this rete seals battery core board fully; form the first pipe protection layer; moreover the periphery of battery component is coated with butyl rubber; sealing forms second pipe protection, makes solar module have good insulation performance and sealing, prevents electric leakage and stops steam to enter battery core board inside; both can guarantee the fail safe of battery component, also prolong the useful life of battery component.And the controllable color of the insulation paint film in the solar battery core board shady face composite film, make battery component more attractive in appearance, meet the requirement of the aesthetics of architecture.
