Add to ORKGPhotoinduced charge separation and recombination in poly(3-hexylthiophene)-fullerene derivative composite films is investigated at low temperature (80 K) by measuring the time-resolved photoinduced absorption due to the infrared active vibrational (IRAV) modes of the polymer in the region 1125–1300 cm-1. The charge separation under 532 nm excitation (repetition rate 5 Hz) is found to be faster than the time resolution of the setup (<200 ps). The decay of charge carriers can be described with power-law kinetics At-α with a single exponent α=0.21 from the subnanosecond to microsecond time scale. Hence, a large percentage of the charges created (~80%) recombine within 30 ns, the remaining long-lived ones recombine on a millisecond time scale. ...
