The dependency of humans on PVs has been remarkably less when compared to the potential possessed by the availability and abundance of the energy being received, the major obstacle being the efficiency of the cell. Multi-junction Solar cells have been an outstanding concept for tackling the problem of efficiency. In this paper, we have presented a model of five layered, four-junction solar cells which concentrates on the conversion of the maximum spectrum of the light energy received by the sun. The concluding energy band diagram, current-voltage characteristics and quantum efficiency have been presented in this paper. The Fill Factor of the cell so developed is 43.61%, and the highest quantum efficiency of the cell is 76.198%. We have compared our results with the previous papers and found a significant increase in the Fill Factor and Qu...

The growing interest of researchers towards the development of this domain reflects the potential in the promises provided by this technology. The possibility of MJPV cells was enhanced with the introduction of Back Surface Field (BSF) in the cell. In this paper, we have presented a detailed comparative study of effects of narrow bandgap (less than 1.1 eV), medium bandgap (1.2 eV to 2 eV) and wide bandgap (higher than 2 eV) semiconductor compounds on SnOX/CdTe/CdS thin-film solar cell. The effects on Quantum Efficiency(QE), Fill Factor (FF), Short circuit current density and open-circuit voltage have been thoroughly studied. After the analysis, it was found that CIGSe as BSF leads to the highest Fill Factor of 75.34% and the average quantum efficiency of 80.5%. The paper also presents the optimized model of the solar cell with different BSF materials for future studi...

Yet, due to low efficiency, this technology has not demonstrated complete reliability and poses tremendous amount of constraints even after the possibility of substantial power outputs. The concept of multi-junction solar cell has provided partial solution to this problem. Since the multi-junction solar cell was developed, its optimization has posed a great challenge for the entire community. The present study has been conducted on Si tandem cell, which is a two-junction three-layered solar cell. Silicon (Si) tandem cell was one of the initial developments in the domain of multi-junction solar cells and is most commercially fabricated photovoltaic cell. In this paper, the optimization challenge of multi-junction solar cells has been attempted with the use of Artificial Neural Network (ANN) technique. Artificial Neural Network was traine...

2021 IEEE 7th World Forum on Internet of Things (WF-IoT)

6th International Conference on Computer Science, Engineering and Information Technology (CSEIT-2019), Nov 23, 2019

This has created numerous challenges and complications for the students looking forward to achieving accurate perception. This paper is presented with an insight to educate the audiences who do not have sufficient knowledge of the Internet of Things (IoT). The scope of this paper expands from the concepts of Information Technology, Digitalization, Wireless Networking, and sensor technologies to the broad arena of IoT. A simple and easily understandable explanation of IoT including applications and impacts to the society has been proposed. This paper exhibits present state-of-the-art experimental research outcomes as extended examples for the reader to develop a comprehensive conceptualization of IoT. Finally, after going through this paper, a layman who does not have any specific knowledge in this field, do build the concepts and understands the advancements behind the buzzword, "IoT."
