摘要

Polymer-based photovoltaic solar cells have been fabricated with high efficiencies of up to 8% by using a photoactive layer with a bulk heterojunction system, which consists of a blend of a low bandgap donor-acceptor (D-π-A)-type conjugated polymer and a fullerene derivative. There are several strategies for modifying the morphology of the photoactive layer so as to create bi-continuous interpenetrating networks in bulk heterojunction systems: slow growth, solvent annealing, thermal annealing, and the selection of the solvent. For poly(3-hexylthiophene) (P3HT), the thermal annealing method can lead to a remarkably high power conversion efficiency (PCE) compared with that of its pristine film, because P3HT consists of an ordered crystalline phase. On the other hand, D-π-A-type copolymers do not usually exhibit higher crystallinity than P3HT even after annealing.
