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 P 3 HT/PCBM interface by addition of an asymmetric block copolymer containing a short organo‐silica precursor.
