| Popis: | Silicon solar cells play a dominant role in the photovoltaic market. However, their manufacturing process is quite expensive and involves complex processes. Therefore, new materials are intensively explored for the aim of potentially higher efficiency and lower cost solar cells. ZnMgO alloy is a very promising transparent conductive oxide layer and which acts as front layer as well as an anti-reflective coating in silicon solar cells reducing costs and complexity of process. Numerical simulation using the SCAPS-1D software enables to find the optimized parameters of p-Si/ZnMgO hetero-junction in comparison with the structure comprising ZnO front layer. Even with the effect of stress caused by the high lattice mismatch at the ZnMgO/Si interface, our calculations show a conversion efficiency of 16.57%.The introduction of a thin layer of hydrogenated amorphous silicon improves the cell output performance to 17.14%.
