Simulation of Anti Reflecting Coating for Improving External Quantum Efficiency of Photovoltaic Cell

Abstract

Due to a dramatic drop in solar module prices/watt peaks, photovoltaic (PV) electricity has become more concentrated over the last decade. Crystallized silicon (c-Si) solar cells have dominated the solar market since their creation, outperforming all other photovoltaic technologies. PV modules are frequently required to work in inclement weather. Outdoor photovoltaic performance is affected by a number of factors, including 1) solar radiation, 2) the shape of the absorbed solar spectrum, 3) ambient temperature, 4) location, 5) wind speed, and 6) aerosols. These parameters, on the other hand, are out of our hands. It does not prevent solar panels from becoming heated on hot days, which has a negative impact on their electrical performance and longevity. To protect the solar cell from various external variables, multiple layers are applied to solar cell modules, including EVA (Ethylene Vinyl Acetate), polyvinyl fluoride sheet (Tedlar), front solar glass, metal frame, and side water seal. One of the main causes of the absorber layer temperature in solar modules rising is this. For single-layer and multi-layer ARC designs, a range of materials are used in the ARC of solar modules. Instead of functioning as a radiative cooler, the ARC can be changed or simple tweaks can be made to improve absorption and lower the temperature of the solar module. Based on light and radiation properties, choose materials for SR-ARC design of solar cells and modules. The chosen material must have very low absorption between 300 and 1200 nm and emit between 8 and 13 m. The annual power generation of a 1kW system in India's complicated environment is determined with the aforesaid efficiency increases and temperature reductions. From a single layer c-Si solar module system, the double layer module of the 1kW system generates 54kWh. Furthermore, the cooling effect was calculated, with the failed component losing 80% of its initial efficiency by the end of 2014, but the two- and three-layer components reached this level by the end of 36. The dual layer SR-ARC coated module system will start producing single layer modules at the end of 26 or 36, with or without replacement.
