HIGHLY EFFICIENT VACUUM-PROCESSED ORGANIC SOLAR CELLS CONTAINING THIENO[3,2ˆB]THIOPHENE-THIAZOLE ORGANIC MOLECULES

摘要

The present invention relates to a novel electron donor used in a photoactive layer of an organic solar cell, a method for manufacturing the same, and to a method for manufacturing an organic solar cell. The organic electron donor is synthesized by using a triphenyl amine derivative as an electron donor part, a thiophene-based unit and a thiazole unit as an intermediate binding part, and a dicyano vinylene unit as an electron acceptor. The organic solar cell according to the present invention obtains average photoelectric conversion efficiency of 6.2% through a vacuum-deposition process.
