Ink of polycarbonate ink-jet printer for flexible or thin-film solar battery and preparation method of same

Abstract

An ink of a polycarbonate (PC) ink-jet printer for a flexible or thin-film solar battery consists of the following materials: 0.5-5 percent of PC resin solution (the solid content of polyester resin in the solution is 1-10 percent), 0.0001-0.1 percent of nano aluminium powder, 0.1-1 percent of viscosity modifier and the balance of solvent. The product manufactured by adopting the method can be sprayed and printed on the upper surface of the flexible or thin-film solar battery through the ink-jet printing technology so as to directly improve the generating efficiency of the flexible or thin-film solar battery.

Description

technical field

[0001] The invention relates to a polycarbonate-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 efficiency of flexible or thin-film solar cells can be directly improved . Background technique

[0002] Polycarbonate (PC) is a polymer with carbonate groups in its molecular chain. According to the structure of ester groups, it can be divided into aliphatic, aromatic, aliphatic-aromatic and other types. Among them, the low mechanical properties of aliphatic and aliphatic-aromatic polycarbonates limit their application in engineering plastics. At present, only aromatic polycarbonate has been industrialized.

[0003] Due to the special structure of polycarbonate, polycarbonate is an amorphous, odorless, tasteless, non-toxic and transparent thermoplastic polymer. It is the only plastic variety with good transparency. It...
