Abstract
We derived relations for time-dependent diffusion coefficient of photoexcited species determined from transient absorption spectra for various types of collision processes controlling decay of photoexcited species of conducting polymers. The method was applied for time-resolved experimental data of polaron pairs decay in 10-nm-thick thin films of regioregular poly(3-hexyl-thiophene).
