Abstract

Abstract : The electronic properties of quantum dots can be tuned by changing the size of particles without any change in their chemical composition. CdSe quantum dots, the sizes of which were controlled by changing the concentrations of Cd and Se precursors, were adsorbed on TiO2 photoelectrodes and used as sensitizers for photovoltaic cells. For applications of CdSe quantum dot as sensitizers, CdSe/TiO2 films on conducting glass were employed in a sandwich-type cell that incorporated a platinum-coated conductive glass and an electrolyte consisting of an I−/I3 − redox. The fill factor (FF) and efficiency for energy conversion (ç) of the photovoltaic cell was 62 % and 0.32 %, respectively.
