General description
Poly(3-hexylthiophene-2,5-diyl) (P3HT) is a polythiophene-based low bandgap semiconducting polymer. It is widely used as anelectron donor material in organic solar cells, OLEDs, and OFETs due to itschemical and thermal stability, controlled synthetic method, goodsemiconducting properties, simple structure, and widecommercial availability. The degree of regioregularity of P3HT has a stronginfluence on its ability to form highly ordered domains.

Application
Poly(3-hexylthiophene-2,5-diyl) can be used as a:
- Active semiconductor to prepare organic field emission transistors. In regioregular P3HT the microcrystalline domains are well constructed by phase-segregated layers of insulating alkali side chains and pi-pi interchain stacking. This leads to high charge mobility and enhances the performance of OFETs.
- Precursor to synthesize P3HT-PCBM( [6,6]-phenyl C61-butyric acid methyl ester) blend thin film. The highcrystallinity of P3HT thin film increases the efficiency of organicphotovoltaic cells.
