In this thesis project, on these glass substrate, by using Sol-Gel Process, pure and gallium- doped ZnO(Zinc oxide) films was covered. Through permeability spectrum thickness of films and optical band gap energy were found.
After the scales were (as electron-volt) reached for solar cells, the glasses, which are cut and shaped, were send.

Optical experiments provide a good way of examining the properties of semiconductors. Particularly measuring the absorption coefficient for various energies gives information about the band gaps of the material. Knowledge of these band gaps is extremely important for understanding the electrical properties of a semiconductor, and is therefore of great practical interest.
