Experimental investigation on the power conversion efficiency performance of molybdenum diselenide and zinc oxide tantalum pentoxide deposited multicrystalline silicon solar cells

Abstract

Global warming and environmental pollution were major concerns for increase in global temperature due to the incomplete combustion of fossil fuels at excessive levels. Limited supply and huge demand of fossil fuels lead to adoption of alternative renewable energy resources. Solar energy resource was widely utilized as a replacement of fossil fuels due to its cleaner, long-term sustainable and pollution free nature. Through photovoltaic effect, solar cells were capable of transforming incident light energy into useful electrical energy. Crystalline silicon solar cells were found to be successful in solar cell industry due to its higher output power generation. Certain part of incident light gets reflected from solar cell surface leading to drop in power conversion efficiency of solar cell. From various literatures, it was evident that reflection loss can be minimized through several techniques resulting in improved photocurrent generation. newlineOne of the effective approaches in minimizing the reflection loses was antireflective surface coatings. Antireflection coatings reduce the light reflection and makes more photons to enter into the depletion region leading to enhanced light transmittance. The main objective of this research work was to minimize the reflection loss through subsequent increase in efficiency of multicrystalline silicon solar cells. Materials with transparent, semiconductive and antireflective nature were utilized as antireflective material. In this work, the synthesis of molybdenum diselenide through hydrothermal process was performed. Then, synthesized materials were deposited over solar cell surface through electrospraying and RF-sputter deposition technique newline
