Abstract
Photoinduced 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 (
