Abstract

Uncrystallized copper indium disulphide (CuInS₂) thin films have been deposited on ITO glass by chemical bath deposition (CBD) in acid conditions. Then polycrystalline CuInS₂ films were obtained after sulfuration in sulfur atmosphere at 300°C, 350°C, 400°C and 450°C for 1.5 hours respectively. The films have been characterized by X-Ray diffraction (XRD), scanning electronic microscopy (SEM), precision surface profiler, energy dispersive X-ray analysis (EDX) and Hall effect measurement system. The results show that with the raising of heat treatment temperature the crystal degree and electrical property of the film are improved. Our work demonstrates the chemical bath deposition in acid conditions is a promising method for deposition of CuInS₂ thin films for solar cells.
