Abstract

A fluorine-modified epoxy resin-based coating for flexible or thin-film solar cells and its preparation method. The coating includes the following components in weight percent: a solution of fluorine-modified epoxy resin-based resin (resin solid content 1-10%)8 ~12%; nano-aluminum powder 0.0001‑0.1%; viscosity modifier 0.1‑1%; the balance is solvent. The products produced by the present invention are coated on the upper surface of flexible or thin-film solar cells by using technologies such as spraying, screen printing and printing, so as to directly improve the power generation efficiency of flexible or thin-film solar cells.

Description

technical field [0001] The invention relates to a fluorine-modified epoxy resin-based coating for flexible or thin-film solar cells and a preparation method thereof. By using the coating to form a layer of light-transmitting coating on the light-incident surface of flexible or thin-film solar cells, the flexibility can be directly improved. or the efficiency of thin-film solar cells. Background technique [0002] Due to the special properties of fluorine atoms, fluorine-containing polymers form a helical structure in which F atoms surround the C-C main chain. The C-F bond is very stable, and the bond energy is 485kJ / mol. The arrangement of fluorine atoms in the outer layer of the carbon skeleton is very tight. The main chain and internal molecules form a shield for protection. Protect the C-C main chain from being damaged by harsh environmental conditions and maintain a high degree of stability. The molecular side groups or side chains of organic fluoropolymer materials co...
