Photophysics and Photocurrent Generation in Polythiophene/Polyfluorene Copolymer Blends

Abstract:

Here, studies on the evolution of photophysics and device performance with annealing of blends of poly(3-hexylthiophene) with the two polyfluorene copolymers poly((9,9-dioctylfluorene)-2,7-diyl-alt-[4,7-bis(3-hexylthien-5-yl)2, 1,3-benzothiadiazole]-2',2"-diyl) (F8TBT) and poly(9,9-dioctylfluorene- cobenzothiadiazole) (F8BT) are reported. In blends with F8TBT, P3HT is found to reorganize at low annealing temperatures (100 °C or below), evidenced by a redshift of both absorption and photolumin...
