•Gamma-ray irradiation effects on photovoltaic thin-film devices based on P3HT conjugated polymer.•Increased light absorption in the red region and PL quenching induced by the irradiation.•Enhancement of the electron mobility, attributable to improved ordering or increased nanodomain size.
Gamma-ray irradiation effects on the photoresponsive thin-film devices based on the regioregular poly(3-hexylthiophene) (RR-P3HT) conjugated polymer have been studied by means of atomic force microscopy, UV–vis absorption, photoluminescence (PL), and time-of-flight measurements. As a result, increased light absorption in the red region and PL quenching induced by the irradiation were observed. Besides, enhancement of the electron/hole mobilities, attributable to improved ordering or increased nanodomain size of the P3HT thin films, was revealed.
