Abstract

Improvements to the optoelectronic and photovoltaic properties of 2-((5′-(4-(diphenylamino)phenyl)-[2,2′-bithiophen]-5-yl)methylene)malononitrile (R1; a donor-acceptor small molecular oligothiophene) are reported through the insertion of planar, conjugated napthalenediimide moiety. The novel donor material was successfully synthesized and exhibited a power conversion efficiency of 3.01% under AM 1.5 G irradiation (100 mW cm-2) when tested in solution-processable bulk heterojunction solar cells with PC61BM as an acceptor material.
