The effect of a mild thermal treatment on the performance of poly(3-allkylthiophene)/fullerene solar cells
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 55degreesC 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.
