Abstract

original image

Planar bilayer organic solar cells with a fluorinated fused subphthalocyanine dimer (FSubPcDimer) as an acceptor and chloroboron (III) subphthalocyanine (SubPc) as a donor obtain a 60% higher Jsc compared to cells using C60 as an acceptor, resulting in a power conversion efficiency of 4%. This is obtained thanks to the important contribution to the photocurrent of the low-bandgap FSubPcDimer.
