Abstract

âº Electronic structure of spin-coated films of PCBM and bis-PCBM was investigated. âº Ionization energy and electron affinity of bis-PCBM are smaller than those of PCBM. âº Electron donation from the side chain to C60-backbone raises the HOMO and LUMO. âº Open circuit voltages of PCBM-based solar cells relates to electron affinities.
