Abstract
Copper indium disulfide (CuInS 2) nano-particles have been synthesized by solvothermal method for absorption layer of solar cells. The CuInS 2 nano-particles can be adsorbed in pores of TiO 2 porous films. The effects of heat-treatment on crystalline structures and sizes of the CuInS 2 nano-particles were investigated. Crystalline structures and sizes were characterized by X-ray diffraction (XRD) and transmission electron microscope (TEM) investigations. Surface morphologies and optical properties were studied by field-emission scanning electron microscope (FESEM) and UV–vis spectra when CuInS 2 were absorbed on TiO 2 films. The results show that the CuInS 2 quantum dots (size is smaller than 10 nm) can be synthesized by solvothermal method at 150 °C. CuInS 2 particles sizes increase with the rise of reaction temperature and time. The CuInS 2 quantum dots can be adsorbed on TiO 2 films well and high-absorptive anodic electrode of solar cells can be prepared. Blue shift of absorption edge was observed as the sizes of CuInS 2 quantum dots decreased.
