The optical properties of TiO2/C in the district from (200-2000 nm) were examined by setting up the composites with wt. % concentration. The optical information evaluated and translated regarding the hypothesis of phonon-assisted direct electronic change; it is watched that the energy is influenced by doping sort of mineral composite utilized. The doping manufactured powders were examined through data analysis to validate the presence of these elements. This investigation for the influence of TiO2 was an addition on the microstructure of the carbon and electrical behavior of the composite was detected, this doped was gotten in a dry place at ambient temperature and its effect was studied from the physical properties of the energy gap. The optical measurement of the specimen was measured as a component of wavelength (λ), absorptivity that exhibit good results to absorb the solar energy for selective surfaces.
