Detailed study of N,N′-(diisopropylphenyl)-terrylene-3,4:11,12-bis(dicarboximide) as electron acceptor for solar cells application

► Properties of terrylene-3,4:11,12-bis(dicarboximide) as electron acceptor for OPV. ► Blended with P3HT efficient charge generation was observed. ► Time of flight electron mobility of 1e−3 cm2/s/V comparable to PCBM. ► Some spectral regions with strong absorption do not participate solar cells' EQE. ► Morphology studies: formation of a hole blocking layer limiting extraction.
