Single phase copper indium gallium sulfide (CIGS) thin films were deposited on a glass substrate by spray pyrolysis technique. Three spray solutions, were prepared with different solution solvents; Ethyl alcohol, Ethylene glycol and 2- Ethoxyethanol. The effect of solvent type on the structural, electrical, optical and surface properties has been investigated. XRD reveals the polycrystalline nature of CIGS films and predominate of (112) plane for all prepared films. Optical investigation showed that the value of absorption coefficient is in the order of 105 cm−1, indicating direct allowed energy gap about 1.5 eV. Thin film prepared using Ethyl alcohol solvent showed better crystallinity with a bigger crystallite size and lowest resistivity of 3.7×10−1 .cm. Three solar cells based on prepared samples with CIGS/n-Si structure was constructed and their I-V curves were measured. We found that the cell fabricated from Ethyl alcohol based spray solution shows the better I-V curve..
