Abstract
We found that the efficiency of bulk-heterojunction (BHJ) solar cells can be enhanced by incorporating a small amount of semiconductor FeS2 nanocrystals (NCs) into the poly(3-hexylthiophene) (P3HT) and (6,6)-phenyl C61-butyric acid methyl ester (PCBM) based active layer. Through optical and nanoscale structure measurements, it is evident that low-cost and non-toxic FeS2 NCs in such devices can efficiently improve charge carrier transport and exciton dissociation. This simple approach for increasing the photocurrent by NCs will be useful for accelerating the development of practical applications using organic solar cells. © 2010 Elsevier B.V.
