Abstract

The invention relates to a fluorine modified epoxy resin-base film for flexible or thin-film solar cells and a preparation method thereof. The film is prepared from the following components in percentage by mass: 8-12% of fluorine modified epoxy resin-base resin solution (the solid content of resin is 1-10%), 0.0001-0.1% of nano aluminum powder and the balance of solvent. The preparation method comprises the following steps: blending the materials, filtering, introducing into a running die head, cooling, drawing, coiling and the like to obtain the fluorine modified epoxy resin-base film for solar cells. The product is attached to the photic surface of the thin-film solar cell or used as an upper packaging film of the solar cell to directly enhance the generating efficiency of the flexible or thin-film solar cell.

Description

technical field [0001] The invention relates to a fluorine-modified epoxy resin base film for a flexible or thin-film solar cell and a preparation method thereof. By using the film to encapsulate the light-incident surface of the flexible or thin-film solar cell, the efficiency of the flexible or thin-film solar cell can be directly improved . Background technique [0002] Among the projects of effective utilization of solar energy: photovoltaic utilization is the fastest growing and most dynamic research field in recent years. Generally, the production of solar cells is mainly based on semiconductor materials, which use photoelectric materials to absorb light energy and generate photoelectric conversion reactions to generate electricity. According to the different materials used, solar cells can be divided into: 1. Silicon solar cells; 2. Solar cells made of inorganic salts such as gallium arsenide III-V compounds, cadmium sulfide, copper indium selenide and other multi-co...
