One Chinese patent application number is 200810242562.1, and open day is to announce a kind of technology of utilizing thin polymer film to carry out the solar components encapsulation on June 3rd, 2009.It is characterized in that utilizing the TPT backboard in the epoxy resin board replacement simple glass assembly, utilize the TPT plate to replace the toughened glass in the existing assembly, thereby reduce its weight.Yet the back side of the ultrathin solar components of this explained hereafter is epoxy resin board or circuit board, and it is poor that outward appearance is felt.And because epoxy resin board is hard, and upper strata EVA is soft, and when lamination was accomplished the back side cut, operate miss very easily caused EVA delamination from the epoxy resin board, thereby exposes the intermediate solar cell sheet.And EVA directly is exposed on end face in the air, very easily causes the aging of whole solar components.
Summary of the invention
The technical problem that the present invention will solve is: for the back side that solves light and thin type solar photovoltaic assembly of the prior art directly is epoxy plate and appearance poor; EVA is exposed to and quickens the aging problem of this solar panels in the air; The invention provides a kind of light and thin type solar photovoltaic assembly and production method thereof; One deck waterproof cloth that pressurizeed at the back side of epoxy resin board can reduce contacting of EVA and air, slows down the aging of EVA.
The technical solution adopted for the present invention to solve the technical problems is: a kind of light and thin type solar photovoltaic assembly and production method thereof; Comprise the clear PET film, upper strata EVA, solar cell string, the middle level EVA that stack gradually; Epoxy resin board, the EVA of lower floor and waterproof cloth, said solar cell string has positive wire and negative wire.
Embodiment one, and the clear PET film surface has been drawn opening, and said positive wire and negative wire are drawn out to outside the light and thin type solar photovoltaic assembly from the opening of clear PET film surface.
Embodiment two, and draw on the waterproof cloth surface has opening, and said positive wire and negative wire are drawn out to outside the light and thin type solar photovoltaic assembly from the opening on waterproof cloth surface.
Embodiment three, and said positive wire and negative wire are drawn out to outside the light and thin type solar photovoltaic assembly along solar cell string plane from the side.
The production method of light and thin type solar photovoltaic assembly has following steps:
A, lamination: get a ultrawhite toughened glass and lie on the workbench; On ultrawhite toughened glass, lay clear PET film, upper strata EVA, welding solar cell string, middle level EVA, epoxy resin board, the EVA of lower floor and waterproof cloth well from the bottom to top successively; Use adhesive tape with being fixed on the ultrawhite toughened glass around the waterproof cloth of the superiors, on waterproof cloth, lay high temperature cloth at last;
B, lamination: the photovoltaic module that lamination is good is put into laminating machine and is carried out lamination, and lamination removes ultrawhite toughened glass and high temperature cloth after accomplishing, and cuts out the waste material that goes periphery unnecessary, obtains the light and thin type solar photovoltaic assembly.
Embodiment one, during lamination, on upper strata EVA and clear PET film, marks opening, with the positive wire of solar cell string and negative wire outside opening is drawn out to assembly.
Embodiment two, during lamination, on EVA of lower floor and waterproof cloth, mark opening, with the positive wire of solar cell string and negative wire outside opening is drawn out to assembly.
Embodiment three, during lamination, the positive wire of solar cell string and the negative wire plane along the solar cell string are drawn out to outside the assembly from the side.
The invention has the beneficial effects as follows that the present invention's one deck waterproof cloth that pressurizeed at the back side of the epoxy resin board of known PET solar photovoltaic assembly can reduce contacting of EVA and air, slows down the aging of EVA.The clear PET film and the undermost waterproof cloth of the superiors are clipped in the middle battery sheet and epoxy resin board, greatly reduce the probability of clear PET film delamination from the epoxy resin board, and the multifarious outward appearance of waterproof cloth can increase the aesthetics of integral product simultaneously.
