Abstract
We use optical spectroscopy to study the recombination dynamics of long-liv ed polarons in thin films of regioregular poly(3-hexylthiophene) (RRPHT). T he modulation-frequency dependence and transient decay of the photoinduced polarons in RRPHT has been measured and modeled using a bimolecular recombi nation mechanism. In both cases, the data can be explained with two relaxat ion times, a slow component in the ms time regime and a faster component in the mus time regime.
