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 optimizing 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 pairing schemes of material for DLARC
is purposed. Current-Voltage and Power-Voltage electrical characteristic of solar cells will be
analysed further. Among the five schemes, the pairing from MgF2 and Si2N3 has yield the highest
efficiency which is 20.94%. It is proven that DLARC can help the solar cell absorb the sunlight
more efficient and will further increase the power conversion efficiency.
