Controlling exciton diffusion and fullerene distribution in photovoltaic blends by side chain modification
Abstract
The influence of crystallinity on exciton diffusion and fullerene distribution<br/>was investigated by blending amorphous and semicrystalline copolymers. We measured exciton diffusion and fluorescence quenching in such blends by dispersing fullerene molecules into them. We find that the diffusion length is more than two times higher in the semicrystalline copolymer than in the amorphous copolymer. We also find that fullerene preferentially mixes into disordered regions of the polymer film. This shows that relatively small differences in molecular structure are important for exciton diffusion and fullerene distribution.
