Abstract

original image

A new approach to improve the power conversion efficiency of polymer bulkheterojunction solar cells by the formation of an embedded passivation layer is demonstrated. In the Communication on page 6311, Ji-Woong Park and co-workers report a simple method to generate silica-like layers along the three-dimensionally intertwined P3HT/PCBM interface by addition of an asymmetric block copolymer containing a short organo-silica precursor.
