Research on base material fabrication for solar cell was done using the vertical Bridgman furnace method and the final products are ingots of CuInSe2. The ingots were then characterized by using optical and electrical characterization methods. Optical characterization includes measuring with X-ray Diffraction (XRD) to determine the parameter value of lattice crystal and using Energy Dispersive Spectroscopy (EDS) to determine the material composition. Extension coefficient, dielectric constant and refraction index were also measured by using elipsometer. Electric characterization was used to classify the type of the material using galvanometer.
