Aiming to evaluate the effect of chain length on the performance of photovoltaic devices, three alternated copolymers were tested. Fluorene, chosen as a common base for comparison was linked to thiophene (Th), ethylene dioxythiophene (EDOT), and benz

The photophysical and photovoltaic properties of three alternated fluorene–thiophene copolymers were studied. With similar structure the copolymers differed by the numbers of thiophene units linked to each fluorene group:one, two and three. The ele
