摘要：

We report an improved quantum dot sensitized solar cell (QDSSC) by loading mercaptopropionic acid (MPA)-capped CdSe QDs on TiO2 film in aqueous solution. Under suitable pH value, a power conversion efficiency of 1.19% and an incident photon to current conversion efficiency of 26% for the QDSSC were obtained at AM1.5G irradiation. The improved performance of QDSSC is attributed to the large loading and good coverage of QDs on TiO2 film with optimal pH value. (C) 2009 Elsevier B.V. All rights reserved.
