    Transparent conductive oxide TCO (ZnO) films were prepared by electro-deposition anodization on n type (100) silicon wafer in the aim to achieve a high efficiency in photovoltaic energy conversion. The ZnO layer were analyzed to improve the heterojunction (HIT) solar cell performance as the FF, Jcc, VCO, η, and the optical properties as QE, X ray diffraction. Measurements show that the preferred orientation of ZnO films grown on Si substrate has (002). The simulations of a-Si/c-Si heterojunction solar cell were carried out to reveal the cell parameters. Our results show that the solar cell heterojunction is hypersensitive to the ZnO layer. The beneficial effect of implementing ZnO front contact for increasing electrical energy conversion properties of HIT solar cell was compared to the cell without the ZnO layer
