Abstract

A fluorine-modified epoxy resin-based film for flexible or thin-film solar cells and a preparation method thereof, the film is made of the following components in the following mass percentages: fluorine-modified epoxy resin-based resin solution (resin solid content 1- 10%) 8-12%; nano aluminum powder 0.0001-0.1%; the balance is solvent. After the above materials are blended, they are filtered and introduced into a casting die, and then cooled, drawn, coiled and other processes to obtain a fluorine-modified epoxy resin base film for solar cells. The product produced by the invention is attached to the light-receiving surface of the thin-film solar cell or used as an upper packaging film of the solar cell to directly improve the power generation 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...
