Study on the Diffusion Rate of the Charge Carrier Transport in Regio-Random P3HT

Article Preview

Abstract:

The hopping mechanism in the regio-random poly (3-hexylthiophene-2,5-diyl) was investigated through study on the diffusion rate of the charge carrier transport from the data of Longitudinal Field (LF) muon-spin-relaxation measurements. Values of the parallel and perpendicular diffusion rate were calculated following the methods applied in NMR. It is found that diffusion rate along the polymer chain slowly decreases from low to high temperatures, while diffusion rate perpendicular to the polymer chain rises significantly from low to high temperatures.
