Experimental investigation on Analyzing the performance of spinel Nanoparticle anti reflection coating On the power conversion efficiency of Polycrystalline solar cells

Abstract

The depletion of natural resources causes a rise in energy demand, prompting researchers to focus on renewable energy supplies. Renewable energy has gained popularity due to the following benefits: production of energy from renewable fuels, long-term sustainability and eco - friendliness. Solar energy is one of the most promising renewable energy in the current scenario. The solar cell is used to convert the light energy received from the sun into electrical energy through the photovoltaic effect which is a physical and chemical phenomenon. The major Part of the incident light rays are reflected back to the surface which causes the decrease in the efficiency due to the reflection loss. Researchers have identified many strategies for controlling reflection losses and thereby enhancing the Power Conversion Efficiency (PCE) of the solar cells. The Anti-Reflection Coating technique (ARC) is one of the most important methods for reducing the reflection loss in solar cells. ARC aids in the reduction of reflection loss and it increases the light absorbing properties of solar cells. This research work focuses on improving the Power Conversion Efficiency of the Polycrystalline solar cells (PSSCS) by using ARC. To achieve improved light trapping efficiency, materials with high anti-reflective properties are needed. Naturally existing materials and chemically combined materials are commonly used as ARC. The magnetic nano particles [M(II) Fe(III)2O4, where M represents Co, Mn, Ni, Zn or Fe] which posses excellent optical , electrical and thermal properties with wide gap semiconductor and also it is used in the variety of applications such as waste water treatment, cancer treatment, nanoelectronics, batteries, etc. But its scope for the application of ARC in solar cells is unexplored. newline
