Facile synthesis of a 56π-electron 1,2-dihydromethano-[60]PCBM and its application for thermally stable polymer solar cells

Abstract

A facile synthesis was employed to make a 56π-electron methano-PC61BM with a very small 1,2-dihydromethano (CH2) group. This new fullerene derivative possesses high electron mobility (0.014 cm2 V−1 s−1) and higher LUMO energy level (0.15 eV) than PC61BM. Bulk hetero-junction devices based on using poly(3-hexylthiophene) and methano-PC61BM as active layer exhibited better performance and thermal stability than those using the PC61BM analogue.
