Enhancing the efficiency of the gallium indium nitride (InGaN) solar cell by optimizing the effective parameters

The present work aims to improve the power and the conversion efficiency of solar cells, using the PC1D simulator, to study the performances of the solar cells based on (InGaN). The paper focuses first on optimization of the technological and geometrical parameters such as doping and the thickness of the layers to investigate their influence on the conversion efficiency of these structures. Then, the paper evaluates the efficiency η for the solar cell with and without Anti-reflection coating ARC on textured surfaces to achieve a final increase of 22.5% of conversion efficiency compared to InGaN standard solar cells.
