Abstract

Golden solar cells: Several positive effects arise from the addition of truncated octahedral Au nanoparticles (ca.70nm diameter) to bulk heterojunction (BHJ) photovoltaic cells fabricated from a variety of donor polymers and PC 70BM as acceptor (see picture). At the optimized blend ratio of Au nanoparticles (5wt%) in the active layer, the power conversion efficiency increased for all polymer/PC70BM systems under study.
