Influence of the Bridging Atom on the Performance of a Low‐Bandgap Bulk Heterojunction Solar Cell

Year: 2009

Type: article

Abstract: Replacing a carbon atom with silicon (see figure) on the main chain of a conjugated polythiophene gives a polysilole with higher crystallinity, improved charge transport, reduced bimolecular recombination, and reduced formation of charge transfer complexes when blended with a fullerene derivative. Optimized bulk heterojunction solar cells using this blend give certified efficiencies of 5.2% under AM1.5 illumination.
