The phase structure and composition of the synthesized pulverized material analyzed by X-ray diffraction (XRD) and energy dispersive analysis of X-rays (EDAX) revealed the chalcopyrite structure and stoichiometry of elements. Thin films of CuInSe2 were deposited onto organically cleaned soda lime glass substrates held at different temperatures (i.e. 300 K to 573 K) using thermal evaporation technique. CuInSe2 thin films were then thermally annealed in a vacuum chamber at 573 K at a base pressure of 10- 2 mbar for 1 h. The effect of substrate temperature (Ts) and thermal annealing (Ta) on structural, compositional, morphological, optical and electrical properties of films were investigated using XRD, transmission electron microscopy, EDAX, atomic force microscopy (AFM), optical transmission measurements and Hall effect techniques. XRD and EDAX studies of CuInSe2 thin films revealed that the films deposited in the substrate temperature range of 423-573 K have preferred orientation of grains along the (112) plane and near stoichiometric composition. AFM analysis indicates that the grain size increases with increase of Ts and Ta. Optical and electrical characterizations of films suggest that CuInSe2 thin films have high absorption coefficient (104 cm- 1) and resistivity value in the interval 10- 2-101 ohm sign cm influenced by Ts and Ta.
