Abstract
In today's world, solar cell efficiency is an important concern. Anti-Reflection Coating serves a critical function in increasing solar cell efficiency. The efficiency of a solar cell is influenced by a variety of factors. The key issue here is reflectivity. Antireflection coatings are used to minimise the solar cell's reflectivity. AR coating is done using semiconductor materials. Generally, the reflectance of solar cells can be reduced up to 3.2% by using an Anti-reflection coating. In this experiment, ZnO is employed as an antireflection coating on the solar cell using the spin coating process. After coating, the solar cell is allowed to cure at a rapid rate of evaporation to get a thin film. UV-Spectrophotometer and Solar Simulator are used to investigate the coated solar cell's optical and electrical features. When the results are compared to the efficiency of a bare silicon solar cell, the coated cell outperforms the unprotected solar cell by 4%.
