Device performance of APFO-3/PCBM solar cells with controlled morphology

Abstract

(Figure Presented) Polymer/fullerene solar cells with three different device structures: A) diffuse bilayer, B) spontaneously formed multilayer, and C) vertically homogenous thin films, are fabricated. The photocurrent/voltage performance is compared and it is found that the self-stratified structure (B) yields the highest energy conversion efficiency. © 2009 WILEY-VCH Verlag GmbH & Co. KGaA.
