Abstract

A new star-shaped D-π-A molecule, tris{4-[5′′-(1,1- dicyanobut-1-en-2-yl)-2,2′-bithiophen-5-yl]phenyl}amine N(Ph-2T-DCN-Et), with high efficiency potential for photovoltaic applications was synthesized. As compared to its analogue S(TPA-bT-DCN), it showed stronger absorption in the region of 350-450 nm and a lower lying highest occupied molecular energy level (HOMO). Solution-processed organic solar cells (OSCs) based on a blend of N(Ph-2T-DCN-Et) and PCBM resulted in a high PCE of 3.1% without any post-treatment. The PCE of N(Ph-2T-DCN-Et) based solar cells was further improved to 3.6% under simulated AM 1.5 by addition of a new additive 4-bromoanisole (BrAni). © 2012 Elsevier B.V. All rights reserved.
