A three‐ to four‐fold increase in power conversion efficiency is reported for poly(3‐alkylthiophene)/fullerene solar cells by simply heating the device to 55 °C for 30 min. This behavior may be due to enhanced diode properties, plus a higher degree of order within the material. The Figure shows the soluble fulleropyrrolidine used as electron acceptor.
