Back Cover: Enhancement of Donor–Acceptor Polymer Bulk Heterojunction Solar Cell Power Conversion Efficiencies by Addition of Au Nanoparticles (Angew. Chem. Int. Ed. 24/2011)
The addition of an optimized amount (5 wt %) of truncated octahedral nanoparticles with 70 nm diameter leads to an increase in power conversion efficiency in bulk heterojunction photovoltaic cells. In their Communication on page 5519 ff., J. H. Park, O O. Park, A. J. Heeger, et al. describe the fabrication of such solar cells from a variety of donor polymers and PC70BM as acceptor.
