摘要：

Quaternary compound Cu2ZnSnSe4 (CZTSe) is one of the most promising absorber layer materials for thin film solar cells. In present work, the CZTSe nanocrystals were successfully synthesized via one pot route, and the influences of reaction temperature on the structural, compositional, morphological and optical properties of as-synthesized CZTSe nanocrystals were investigated in detail via X-ray powder diffraction (XRD), energy dispersive X-ray spectrometry (EDS), transmission electron microscopy (TEM) and UV-Vis spectrophotometry, respectively. The characterization results of as-synthesized nanocrystals, under optimal synthesis condition (250 degrees C, 1 h), indicated that the nanocrystals was monodispersed with polycrystalline, the size was in the range of 10-15 nm, and the band gap energy was around 1.44 eV which is very closed to the best band gap energy for the solar cell. All results suggested that the as-synthesized CZTSe nanocrystals were good light absorber layer material for thin film solar cell.
