Impact of AM1.5G Spectrum on Photovoltaic (PV) Technology: Bridging Laboratory Testing and Real-World Solar Energy Harvesting

A crucial benchmark for assessing photovoltaic (PV) technology is the AM 1.5G spectrum, which simulates the usual solar irradiation levels found in most of the world. This research explores how the AM 1.5G spectrum affects the performance of double perovskite/CIGS-based solar cell, with a focus on bridging the gap between controlled laboratory testing and real-world energy harvesting applications. The AM 1.5G spectrum provides a realistic simulation of sunlight, allowing for precise measurement of solar cell efficiency metrics and valid comparisons across various technologies and manufacturers. The research focuses on how this standard spectrum affects the design and optimization of both traditional silicon-based solar cells and innovative thin-film technologies. The goal of this research is to improve the overall accuracy of solar energy harvesting in a variety of climatic circumstances and contribute to the ongoing development of PV technologies by combining insights from testing environments and real-world deployment scenarios. Finally, the findings highlight the importance of standardized testing techniques that simulate real-world situations in order to accelerate the global adoption of solar energy solutions.
