摘要：

Metal chalcogenide complex (MCC) has been reported as a promising exchanger to link quantum dots onto photoanodes in quantum dot sensitized solar cells, which provides better chemical connectivity and electronic conductivity. However, the reported efficiencies are far lower than average efficiencies for quantum dot sensitized solar cells using traditional exchangers, which is majorly ascribed to the low short current densities. Serious electron recombination among MCC connected quantum dots are proposed and proved according to transient photoluminescent spectra, which reduces short current densities.
