Abstract
In this paper, a novel solar cell based on hydrogenated amorphous silicon (a-Si:H) and metal oxides CuO is proposed. Using the one-dimensional computer code SCAPS-1D and under the AM1.5G spectrum, the a-Si:H(p)/CuO (P)/a-Si:H(n) solar cell is simulated and studied. The performance of solar cells, especially short-circuit current (Jsc), fill factor (FF) and conversion efficiency (ƞ), has been significantly improved by the CuO metal oxide absorber layer. The influence of the thickness of the absorbing layer, the band-gap of the CuO absorbing layer, the concentration of the acceptor, as well as the effect of working temperature on the photovoltaic parameters of the proposed solar cell are examined and promising results have been obtained. Indeed, the yield goes from 11.29 % for conventional p-i-n hydrogenated amorphous silicon to 26.39 % for the new hetero-junction structure.
