Abstract :
Cadmim Indium sulfide (CdIn2S4) thin films composed of wedgelike crystals were prepared on fluorine-doped tin oxide substrate by a tartaric acid assisted hydrothermal method. The tartaric acid was found to play an important role in the formation of the final product. The formation mechanism of the CdIn2S4 film was also discussed. The optical properties and microstructure of the CdIn2S4 films were characterized by X-ray diffraction, field-emission scanning electron microscopy, and UV-vis absorption spectroscopy. The results revealed that the wedgelike CdIn2S4 thin films were crystallized in the cubic spinel structure. The analysis of optical absorption data shows bandgap energy to be 2.46 eV which is optimal for photovoltaic applications.
