Abstract

An inkjet printer ink for flexible or thin-film solar cells and a preparation method thereof, comprising the following components by weight percentage: polyester resin solution (the solid content of polyester resin in the solution is 1-10%) 0.5-5%; Nano aluminum powder 0.0001‑0.1%; viscosity modifier 0.1‑1%; the balance is solvent. The products produced by the present invention are printed on the upper surface of flexible or thin-film solar cells by using ink-jet printing technology, 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 polyester-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 the flexible or thin-film solar cells, the efficiency of the flexible or thin-film solar cells can be directly improved. Background technique [0002] Polyester is a general term for polymers obtained by polycondensation of polyols and polyacids, including saturated polyesters and unsaturated polyesters. The molecular structure of polyester is highly symmetrical, and it has a certain crystal orientation ability, so it has high film-forming and formability. It mainly refers to polyethylene terephthalate (PET), and customarily also includes linear thermoplastic resins such as polybutylene terephthalate (PBT) and polyarylate. It is a kind of engineering plastic with excellent performance and wide application. It can also be made into polyester fiber and polyester ...
