Abstract

The invention relates to a fluoridated polyimide-base ink-jet printer ink for solar cells and a preparation method thereof. The ink is prepared from the following components in percentage by weight: 0.5-5% of fluoridated polyamide resin 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] A fluorinated polyimide-based inkjet printer ink for flexible or thin-film solar cells and a preparation method thereof, the efficiency of the flexible or thin-film solar cells can be directly improved by using the ink to print on the light-incident surface of the flexible or thin-film solar cells. Background technique [0002] Due to the high-tech material aromatic polyimide (PI) resin is insoluble, refractory, the highest level of heat resistance, cold resistance, oxidation resistance, radiation resistance, chemical resistance, good mechanical and electrical properties and are widely used in many fields. In particular, optically transparent PI films have special applications in some fields, such as flexible solar radiation protection materials, solar cell substrate materials, flexible transparent conductive film substrate materials, alignment film materials for liquid crystal displays, optical waveguide materials and planar materials in the communica...
