Abstract

The invention relates to a fluorine modified epoxy resin-base ink for thin-film solar cells and a preparation method thereof. The ink is prepared from the following components in percentage by mass: 0.5-5% of fluorine modified epoxy resin-base solution (the solid content of resin is 1-10%), 0.0001-0.1% of nano aluminum powder, 0.1-1% of viscosity regulator and the balance of solvent. The product can directly enhance the generating efficiency of the flexible or thin-film solar cell when being printed to the upper surface of the flexible or thin-film solar cell by an ink-jet printing technique.

Description

technical field [0001] The invention relates to a fluorine-modified epoxy resin-based inkjet printer ink for flexible or thin-film solar cells and a preparation method thereof. By using the ink to print on the light-incident surface of flexible or thin-film solar cells, the flexibility or thin-film can be directly improved. The efficiency of 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 on the periphery. The C-F bond is very stable, with a bond energy of 485 kJ / mol. The fluorine atoms are arranged very tightly in the outer layer of the carbon skeleton, which can Form a shielding protection for the main chain and internal molecules. 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 conta...
