A Performance study on copper indium selenide and Zinc Sulphide quantum dots for solar cell applications

Abstract

The solar cell is an electrical device that directly transforms optical light into newlineelectrical energy. Monocrystalline and polycrystalline silicon solar cells are penetrating newlinethe solar cell market. However, the price of these solar cells is too high. With the newlineadvancement of thin-film technology, this has considerably diminished. Despite newlineextensive research and development efforts, Quantum dots (QDs) photovoltaic cells still newlinefall short of their potential efficiency. Quantum dot band gaps may be modified, and newlinecell interfaces can be optimized to boost light utilization capacity to improve photo newlineconversion efficiency. The quantum dot absorber in these solar cells is Copper Indium newlineSelenide (CuInSe2 or simply CIS). The CIS alloyed with ZnS to create Copper Indium newlineSelenide-Zinc Sulphide (CISZS) quantum dots to obtain an adjustable bandgap, newlineimproved photoluminescence, decreased surface defect density, and greater lightharvesting newlineefficiency. The CISZS sensitizer that is the outcome of this process has better newlinephotoelectric properties and higher chemical stability. Silvaco-Atlas modelling newlinesoftware measures such as power conversion efficiency, open-circuit voltage (Voc), newlineshort-circuit current density (Jsc) and fill-factor (FF) for each of the CIS and CISZS newlinesolar cells. A solar cell with CISZS has better photo conversion efficiency compared to newlineCIS solar cells. The highest efficiency of power conversion attained by QDs solar cells, newlinewhich have better optical and electrical characteristics than hazardous quantum dot newlineabsorbers made of lead and cadmium chalcogenide. newlinePhotovoltaic-powered electric transportation systems are gaining global newlinemomentum owing to their superior enactment and zero carbon emissions. With a newlinegrowing number of electric vehicles (EVs) on the road, the implementation of efficient newlineand well-organized charging stations is extremely indispensable. In this research work, newlinethe feasibility of creating a charging station for plug-in-hybrid EVs at an educational newlineinstitution has been investigated. The statistics related to th
