Abstract

and FF. Furthermore, transient photovoltage and photocurrent measurements revealed a long carrier lifetime of 22.30 µs and a short extraction time of 904 ns in the ternary system, which were beneficial for the OSC performance. In addition, the incorporation of PBDB-T resulted in reduced non-radiative recombination in the device through efficient energy transfer. The role of PBDB-T in improving the performance of the PTB7-Th:COi8DFIC-based host binary was investigated through systematic photophysical, morphological and electrical characterizations.
