摘要：

In this work, we report the quantum dot sensitized solar cells (QDSSCs) by loading CdSe QDs on TiO2 films via different bifunctional linkers. Three different linker molecules as ligands were employed to anchor QDs to TiO2 film: 4-mercaptobutyric acid (MBA), mercaptosuccinic acid (MSA) and sodium 3-mercapto-1-propanesulfonate (MPS). Electrochemical impedance spectroscopy (EIS) demonstrated that the electron lifetime for QDSSC based on MPS-modified TiO2 was longer than those for QDSSCs based on MBA- and MSA-modified TiO2, which indicated that interface charge recombination was reduced by MPS linker. The power conversion efficiency (PCE) of similar to 1% was achieved for MPS-modified QDSSC.
