Optical Properties of Nano-CuInSi thin Films Prepared by Multilayer Synthesized Method
Thin Nano-CuInSi films have been prepared by multilayer synthesized method using magnetron sputtering technology, and followed by annealing in N2 atmosphere at different temperatures. The structures of CuInSi films were detected by X-ray diffraction(XRD); X-ray diffraction studies of the annealed films indicate the presence of CuInSi, the peak of main crystal phase is at 20=42.450°; the morphology of the film surface was studied by SEM. The SEM images show that the crystalline of the film prepared by multilayer synthesized method was granulated. The transmittance (T) spectra of the films were measured by Shimadzu UV-2450 double beam spectrophotometer. The calculated absorption coefficient is larger than 105 cm-1 when the wavelength is shorter than 750 nm. The band gap has been estimated from the optical absorption studies and found to be about 1.47 eV, but changes with purity of CuInSi. CuInSi thin film is a potential absorber layer material applied in solar cells and photoelectric automatic control.
