Numerical modelling of high-efficiency Si solar cell using various DLARCs

Solar cells, also known as photovoltaic cells, convert sunlight into electricity, reducing human reliance on fossil fuels. Understanding historical advancements, principles, and various types of solar cells is crucial for optimising this sustainable energy alternative and advancing the use of clean and renewable energy sources. This study investigates the impact of double-layer antireflection coating (DLARC) materials on silicon solar cells, focusing on their role in reducing reflectance across various wavelengths. There are five material pairing schemes intended for DLARC. The current-voltage and power-voltage electrical characteristics of solar cells will be analysed further. Among the five schemes, the pairing from MgF2 and Si2N3 has yielded the highest efficiency, which is 20.94%. It is proven that DLARC can improve the solar cell’s ability to absorb sunlight and will further increase the power conversion efficiency.
