Abstract

The invention relates to a photocuring 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 parts by weight: 100 parts of fluorine modified epoxy resin, 0.0001-0.1 part of nano aluminum powder, 0.5-1.25 parts of photocuring agent, 0.1-0.2 part of antioxidant, 0.1-0.2 part of ultraviolet absorbent and 0.1-0.2 part of amine photostabilizer. The preparation method comprises the following steps: blending and extruding the fluorine modified epoxy resin, nano aluminum powder, photocuring agent, antioxidant, hindered amine photostabilizer and the like by a screw blending and extrusion apparatus, filtering, introducing into a running die head, cooling, drawing, coiling and the like to obtain the photocuring fluorine modified epoxy resin-base film for flexible or thin-film 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 photocurable fluorine-modified epoxy resin base film for flexible or thin-film solar cells and a preparation method thereof. By using the film to encapsulate the light-incident surface of flexible or thin-film solar cells, the flexible or thin-film solar cells can be directly improved. s efficiency. 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 mul...
