Abstract

A small molecule/fullerene binary acceptor system was developed for achieving high performance polymer solar cells. The additional blended small molecule acceptor not only improved the utilization of solar energy, but also achieved balanced carrier mobilities, leading to a significantly enhanced power conversion efficiency (PCE) up to 9.55%.
