Simplified Method to Compare the Performance of a Solar Cell Under Different Optical Conditions and Orientations (Englisch)

The electrification of the modern world will increase the relevance of Renewable Energy Sources (RES). Specifically, Photovoltaic (PV) technologies are expected to be the fastest developing energy generation source. Given the efficiency challenges that these technologies come with, it is necessary to create techniques that allow improving and maximizing their power generation. This paper presents a simple approach to compare the performance of solar cells, using Short-Circuit Current (Isc), Open-Circuit Voltage (Voc) and taking advantage of Internet of Things (IoT) technologies to create a device capable of comparing the performance of multiple cells and plotting real-time results at the same time. Two experiments are carried out to compare different optical covers and different orientations, where according to the device’s measurements, a flat cover performed \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$11.5\%$$\end{document} better than a triangular cover, and western oriented cells performed \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$18.7\%$$\end{document} better that eastern oriented ones. Thus, the device was capable of giving insights for design decisions.
