Abstract : In this part was prepared composite second Slinat copper and indium in a fusion of direct components of the composite was also prepared thin sections of this article using the technique evaporation discharged from the evaporator single, and was obtained models diffraction of X-ray which showed the stability of the compound, whether in the form of powder or in segments prepared by evaporation. Has been appointed the constants of the optical slices prepared (refractive index of the real N, and the refractive index give K) using the calculation methods developed by the computer, it has been measured permeability and reflectivity of the light falling vertically on the slide in the spectral and broad stretches of the visible spectrum 400 nm to the infrared region 2000 nm. The results showed that the value of the optical constants do not change the future, the surface temperature, was calculated the value of absorption coefficient and change with the light energy in the spectral range in question. 1. Analyzed the results possible conclusion is that there Antqalin directly in the segments of second Slinat copper, indium, as the first transition of the kind is allowed and the amount of energy gap of 1.030 eV, while the second is the transition is allowed and the energy gap of $ 1.254 electron volts. 2. Possible to determine the top of the activation energy for this type of cells and found to be equivalent to 1950 electron volts. 3. This project also addressed the expense constants cells manufactured with an area of ​​250 cm 2 and under lighting Mellia 50 W / cm 2 has been found as follows: 1 - open circuit voltage VOC) = 3670) V 2 - closed-circuit current density of JS = 14.4 mA / cm 2 3 - fragmented resistance RSH = 236 ohms 4 - coefficient of fullness FF = 360% 5 - cell efficiency N = 3.9%
