Abstract

original image

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