[6, 6]‐Phenyl‐C61‐Butyric Acid Dimethylamino Ester as a Cathode Buffer Layer for High‐Performance Polymer Solar Cells. Issue 12 (23rd July 2013) - Li, Shusheng
Abstract Two [6, 6]‐phenyl‐C61‐butyric acid methyl ester (PCBM) derivatives with side‐chain‐attaching amine end groups, PCBDAN and PCBDANI, are synthesized. Both PCBDAN and PCBDANI show excellent photovoltaic performance as cathode buffer layers to replace Ca in polymer solar cells.
