The TiO2 /OA-CdSe photoanode in a two-electrode device exhibited a photon-to-current conversion efficiency of 17.5% at 400 nm. At AM1.5G irradiation with 100 mW/ cm2 light intensity, the QDSSCs based on OA-capped CdSe showed a power conversion efficiency of about 1%. The function of OA was to increase QD loading, extend the absorption range and possibly suppress the surface recombination. © 2009 American Institute of Physics.[SDGs]SDG7Light intensities; Photoanode; Photon-to-current conversion efficiencies; Power conversion efficiencies; Quantum dots; Surface recombinations; Acids; Cadmium alloys; Cadmium compounds; Conversion efficiency; Oleic acid; Photovoltaic cells; Semiconductor quantum dots; Solar cells; Solar energy; Semiconducting cadmium compoundsjournal article10.1063/1.31172212-s2.0-65249104493WOS:000265285200080
