In this work two solar cell types were fabricated. The first type is FTO/ CuO/ ZnO/ Al and the second type is FTO/ ZnO/ CuO/ Al. Six samples were prepared from each type. The efficiency for each type was obtained. It was found that the efficiency of FTO/ ZnO/ CuO/ Al is in the range  , while the efficiency of FTO/ CuO/ ZnO/ Al is in the range   . The difference may be attributed to the fact that FTO and CnO acts as p- type semiconductor, while ZnO act an n- type semiconductor. Thus the first type acts as pnp component thus have low efficiency, while the second type acts ppn component and have relatively high efficiency

Keywords:   Solar cell, fabricated, efficiency, semiconductor
