CuInSe2 thin films were prepared successfully with the chemical spray pyrolysis as a function of Cu/In atomic ratios and variation of selenium contents. The X-ray diffraction, UV-visible spectroscopy, the Hall effect measurement and scanning electron microscopy were carried out for the compositional and structural analysis. The effects of the Cu/In ratio and selenium concentration were observed in the XRD, SEM, UV-visible spectrum and the Hall effect measurement analysis for fabricated thin films. The XRD and UV-visible analysis results showed an increase or decrease of crystallinity and shift of transmittance tendency depending on the copper and selenium content. The thin film grain size was increased with the increase of copper content. In the thin films, the variation of Cu/In ratios between 0.8 to 1 showed an increase on hole density, but a decrease of Hall mobility and resistivity. We suggest the formation of CuxSe phase particles or layers depends on the spray solution. Based on these results, we will fabricate and characterize CISe/CIGSe thin film solar cells in further work.
