Performance evaluation of power conversion efficiency attainment in polycrystalline silicon solar cells through sputter and spin coated molybdenum disulphide antireflecting layer

Abstract

The energy demand increases day-by-day due to over exploitation newlineof fossil fuels. Fossil fuels based energy was the major source of energy in the newlinepast as well as present world. Due to higher demand of fossil fuels, the overall newlinecost increases and supply decreases. Hence, a renewable energy source comes newlineinto picture. The major reasons for preferring renewable energy sources in newlineplace of conventional fossil fuel energy sources are non-depleting nature, newlinesustainable for longer period, clean and zero percent CO2 emission. Among newlineall renewable energy sources, solar energy was most promising one. Through newlinephotovoltaic effect, the incident light energy can be converted into useful newlineelectrical energy with the help of solar cell. newlineFuturistic world will surely rely on the solar energy sources. Hence, newlinesolar cell finds more applications at present and in near future. Some of the newlinelosses incurred during the photo generation process into the solar cell are newlineoptical and electrical loses. By minimizing the reflection of incident light newlinerays, there is a chance of trapping more photons into the depletion region. newlineThis results in enhanced power output of solar cell with antireflective surface. newlineAntireflective surface coatings were capable of minimizing the scattering of newlineincident light from the solar cell surface. Antireflective materials for solar cell newlineapplications should be transparent, possess wide energy band gap and newlinesemiconductive in nature. In this research work, transition metal chalcogenide newlineMoS2 was considered as an antireflection material. The coated thin films over newlinesolar cells were obtained through spin and sputter deposition techniques. newlineHowever, the preferred coating material and techniques remain unexplored. newline newline
