Paper Abstract

A comparison study between a block copolymer and blend samples (D/A; donor/acceptor) revealed that their optoelectronic properties change significantly in different morphologies due to different processing conditions. The study shows that the photovoltaic performance of a block copolymer is better than that of corresponding donor/acceptor simple blend devices due to smaller scale (5-10 nanometers) donor/acceptor phase separation in the block copolymer, and that thermal annealing generally improves OE property due to potential better molecular packing.
