【 摘 要 】

The chalcopyrite-type CuInSe2 is a remarkable material for thin film solar cells owing to its electronic structure and optical response. Single-phase sphere-like CuInSe2 nanocrystallite particles were prepared by a facile noninjection method with triethanolamine as the complexing agent and the solvent simultaneously. The period of the reaction was the key to form single-phase CuInSe2 nanocrystals at 240 oC. TEM, XRD, XPS, EDX investigations were performed to characterize the morphology and the detailed structure of as-synthesized CuInSe2 nanocrystals. All of the analysis results proved that the synthesized nanocrystals were pure phase and close to the stoichiometric ratio rather than a simple mixture. The band gap of the obtained CuInSe2 nanocrystals was 1.03 ± 0.03 eV.
