摘要

Organic photovoltaic (OPV) cells were fabricated via vacuum vapor deposition with {4-[2-(3-dicyanomethylidene-5,5-dimethylcyclohexenyl)vinyl]phenyl}di(1-naphthyl)amine (DNP-2CN) as the electron donor,and fullerene (C60) as the electron acceptor. A thin film (10 nm) of tris(8-quinolinolato)aluminum (Alq3) was adopted as the buffer layer. A device based on this DNP-2CN exhibited an open circuit voltage (Voc) of 370 mV, a short-circuit current density (Jsc) of 0.61 mA·cm-2, and a white-light power conversion efficiency (η) of 0.09%(AM1.5, 75 mW·cm-2).
