AbstractQuantum dot sensitized solar cells have been made by using nanocrystalline titania as photocatalyst, sensitized in the Visible by a combination of quantum dot sensitizers: first a layer of CdS, followed by deposition of CdSe and finally a passivation layer of ZnS on the top. An inox grid was used as anode electrode and its functionality was compared with that of transparent fluorine-doped tin oxide (FTO) electrodes. Cu

Suppressing the charge recombination at the interface of photoanode/electrolyte is the crucial way to improve the quantum dot sensitized solar cells (QDSSCs) performance. In this scenario, ZnS/SiO2 blocking layer was deposited on TiO2/CuInS2 QDs to inhibit the charge recombination at photoanode/electrolyte interface. As a result, the TiO2/CuInS2/ZnS/SiO2 based QDSSCs delivers a power conversion efficiency (η) value of 4.63%, which is much higher than the TiO2/CuInS2 (2.15%) and TiO2/CuInS2/ZnS (3.23%) based QDSSCs. Impedance spectroscopy and open circuit voltage decay analyses indicate that ZnS/SiO2 passivation layer on TiO2/CuInS2 suppress the charge recombination at the interface of photoanode/electrolyte and enhance the electron lifetime.
