Spin dynamics of light-induced charge separation in composites of semiconducting polymers and PC₆₀BM revealed using Q-band pulse EPR

Abstract

was extracted. In composites with low-efficient polymers the contribution of the SCPP to the in-phase ESE signal is high, while in composites with high-efficient polymers it is low. This finding can be used as a selection criterion of charge separation efficiency in the polymer/fullerene composites.
