英文摘要: Here we report the first synthesis of ultrasmall CuInSe2 quantum dots (QDs) with diameters below the exciton Bohr radius 10.6 nm by a solvothermal method. The synthesis is conducted in oleylamine without any organometallic precursors. The quantum confinement effect has been identified in the optical absorption spectra. Through pre-loading CuInSe2 QDs on TiO2 film, a good electron transfer dynamics could be observed on the CdS/CuInSe2/TiO2 film. Under one sun of simulated irradiation, the resultant quantum dot sensitized solar cell based on CdS/CuInSe2 exhibited a power conversion efficiency of about 2.27%, which was 55% higher than that of the single CdS sensitized solar cell. It indicates that CuInSe2 QDs have great potential in photovoltaic applications.
