Summary: Solar energy, as a free renewable energy source, is a suitable alternative to fossil fuels. Thin-film solar cells, while cost-effective, have low efficiency. In this research, a new architecture for a 200 nm Si solar cell is proposed, utilizing a latticed Al2O3 ARC as an antireflection coating and Ag disk shape nanoparticles on the front surface. Additionally, an Ag film is used as a back-reflector. With this design, the short-circuit current density and efficiency are significantly improved compared to the bare cell.

Summary: Increasing the efficiency of silicon heterojunction solar cells requires enhancing sunlight utilization through light management. This study demonstrates that using multilayer anti-reflection coatings can significantly improve the photovoltaic performance of these cells. Specifically, a 90/21/40 nm SiO2/SiN(x)/ITO anti-reflective layer structure reduces the reflectance of the cells to 0.94% and increases the current density by 4.34% compared to conventional cells. This research provides a promising and cost-effective approach to achieving higher light utilization and promoting the photovoltaic characteristics of silicon heterojunction solar cells.
