Thin film solar cells, with structure TCO/CdS/CdTe/Cu, were fabricated using the transparent conducting oxides (TCOs) SnO 2 :F, deposited by spray pyrolysis, and ZnO, deposited by reactive evaporation, as transparent electrodes. The TCO/CdS system with the CdS layer deposited by CBD (chemical bath deposition) method acts in the cell as an optical window and the CdTe deposited by CSS (close space sublimation) method acts as absorber layer, being the unique active layer of the cell. Details of the technological aspects of the solar cells fabrication as well as a discussion to explain the effect of the TCO layer on the solar cell performance will be given. The best results obtained in this work were: open circuit voltage of 0.57 V, short circuit current of 13 mA/cm 2 , fill factor of 0.63 and conversion efficiency of 5.8%.
