Multifunctional Device for Measuring and Monitoring Parameters of a Photovoltaic Module | Chapter 12 | Research and Developments in Engineering Research Vol. 4

 In this work, analyzes of existing devices for measuring the current-voltage characteristic were carried out in order to compare several devices. The purpose of this work is to develop a device for measuring the current-voltage characteristics of photovoltaic modules and the environmental factors affecting them. The paper discusses a system for monitoring solar module parameters that measure air temperature, module temperature, solar radiation, wind speed, current-voltage characteristic, maximum power point (MPP), efficiency, and fill factor (FF) and stores the data in a computer. The system is constructed around a programmable microcontroller with an analog-to-digital converter built in. The suggested system's program code also includes an algorithm for determining the maximum power point of the solar module. Because every parameter are taken into account automatically and written to the computer in the form of tables, the system performs all measurements in real time and is simple to use.  In order to compare the suggested monitoring system with alternative commercial measuring equipment, the research looked at their properties. The proposal includes a circuit diagram for a monitoring system as well as an electrical circuit to measure current-voltage characteristics.

A DFT Study on Theoretical Investigation of Application of Combining Pristine C60 and doped C60 with Silicon and Germanium Atoms for Solar cells | Chapter 4 | Challenges and Advances in Chemical Science Vol. 3

 In the recent decade, there has been a lot of research into solar energy and how it can be converted to electricity. A p-type semiconductor serves as the donor, while an n-type semiconductor serves as the acceptor in solar cells. In an organic solar cell, organic polymers are employed as organic semiconductors. This study looks at the basic structure of a solar cell using Fullerene C60 as a donor and C60 doped derivatives with Silicon and Germanium atoms as acceptors. This study examines the theoretical UV-VIS spectrum of the chosen donors-acceptors, as well as their absorption wavelengths, oscillator strength, and maximum coefficient absorptions of these solar cells, in addition to employing associated equations.
