摘要：

The performance of polymer/C-60 photovoltaic cells doped with organic small molecules is investigated. It is shown that the small molecules with better hole-transporting mobility are helpful to the performance improvement of photovoltaic cells, while those molecules with better electron-transporting mobility are not. Hole-transporting material, triplephenylamine (TPA), is found to be the best dopant in the photovoltaic cells compared with the cells (MEH-PPV:C-60=1:1) without the dopant. With the addition of 40% (w/w) TPA, the short-circuit current increases five folds, and the white-light energy conversion efficiency reaches 0.24%.
