Abstract

The invention discloses organic amine derivative doped organic photoactive layer composite ink as well as a preparation method and application thereof. The organic photoactive layer composite ink comprises an electron donor material, an electron acceptor material, an organic amine derivative and an organic solvent, and the organic amine derivative comprises an organic amine derivative with a structure represented by a formula (1), wherein R1, R2, R3 and R4 comprises hydrogen, a substituted or unsubstituted C1-C20 alkyl group, a C1-C20 heteroalkyl group or a substituted or unsubstituted modified aromatic or heteroaromatic pi conjugated unit derivative; or a substituted or substituted five-membered or six-membered cyclic structure is formed between R1 and R2 and between R3 and R4; and R5 andR6 comprise hydrogen, C1-C5 alkyl and C1-C5 aminoalkyl, and R5 and R6 are not hydrogen or alkyl at the same time. The selection of the organic amine derivative has great influence on the stability ofa device, and the light stability of a photoactive layer material can be significantly improved.

Description

technical field [0001] The invention relates to a photoactive layer composite ink material of an organic solar cell, in particular to an organic photoactive layer composite ink doped with organic amine derivatives and a preparation method thereof, as well as a high-stability organic solar cell and a composite ink formed by using the same The preparation method belongs to the technical field of photoelectric functional materials and devices. Background technique [0002] Organic solar cells have attracted widespread attention due to their advantages such as low cost, light weight, good bending performance, and large-area printing. In recent years, with the unremitting efforts of scientists, the photoelectric conversion efficiency of organic solar cells has exceeded 11%, gradually approaching the threshold of commercialization. In contrast, the stable performance of current organic solar cell devices is far from meeting the application requirements. [0003] A large number o...
