Abstract

The use of renewable energy, especially solar photovoltaic, has grown more and more necessary in the context of the diversification of the use of natural resources. Sb2S3 is emerged as an attractive candidate for today's thin-film solar cells due to its band gap of 1.65 eV and high absorption coefficient greater than 105 cm-1. Cadmium Sulfide is the most commonly used buffer layer material in thin film solar cells, but cadmium is a metal that causes severe toxicity in humans and the environment. This article tried to avoid cadmium for solar cell generation. This paper presents the findings of a computer simulation analysis of a thin film solar cell based on a p-type Sb2S3 absorber layer and an n-type ZnSe buffer layer in a structure of (Sb2S3/ZnSe/i-ZnO/ZnO: Al) utilizing simulation software (SCAPS-1D). The simulation included detailed configuration optimization for the thickness of the absorber layer, buffer layer, defect density, temperature, and series-shunt resistance. In this work, the Efficiency (η), Fill Factor (FF), Open-circuit Voltage (Voc), and short-circuit current (Jsc) have been measured by varying thickness of absorber layer in the range of 0.5µm to 4 µm and by varying thickness of buffer layer in the range of 0.05 µm to 0.1µm. The optimized solar cell shows an efficiency of 20.03% when the absorber layer thickness is 4µm and the buffer layer thickness is 0.08µm.

Abstract

The main objective of this study is to review microgrids from both a technical and financial standpoint in order to electrify rural places. Making a microgrid in rural area is challenging due to its technical and economical perspective. Technical and Economic analysis could investigate power quality and system stability for a local community in a nation. The technical and economic aspects of microgrid design and operation are covered, along with a number of other parts such power sources, energy storage, and control systems. Installation and maintenance cost has been discussed with respect to technological and economical view point in this paper. The report ends with a review of the prospects and problems for implementing microgrids in remote locations. Various challenges of microgrid and prospective solutions have also been discussed for the betterment of microgrid technically and economically. Microgrid planning has also been explained in this paper in rural regions entails the process of creating, developing, and deploying microgrid systems to provide dependable and sustainable power. Some influential factors such as technological factors, economic factors, socio-political factors and environmental factors on which microgrid depends have been discussed in this paper. The study offers a thorough discussion of microgrids as a potential method for electrifying rural areas. The study shows that microgrid is economically more beneficial to be developed in any rural area, as well as complying the minimum technical requirement of local grid code. Therefore, it can be said that any locality of a nation is a more viable and economic location to implement microgrid for the development. This review will assist the decision-makers in adopting microgrids for the electrification of rural areas and hold establishing regulations that are helpful and clear for the operation and integration of microgrids. System effectiveness, energy storage, and grid management breakthroughs may result from research and development of microgrid technology.
