دراسة تجريبية لتأثير الأشعة فوق البنفسجية على خصائص منحنيات الجهد والتيار ومنحنيات القدرة لخلية كهروضوئية باستخدام نوعين مختلفين من العدسات الواقية

الملخص

This study presents an experimental investigation into the impact of UV radiation on the I-V and P-V curve characteristics of a photovoltaic cell using two different types of protective lenses. The research aims to compare how each lens material responds to UV exposure, analyzing changes in key PV parameters such as open-circuit voltage (Vₒₑ), short-circuit current (Iₛₑ), fill factor (FF), and maximum power output (Pₘₐₓ). The findings will provide insights into the durability and performance of lens materials under UV stress, contributing to the development of more efficient and long-lasting PV systems. A reference cell is also used to calibrate the system in terms of I-V curve to compare it with the two types of protective lenses. Reference cells are crucial for calibrating solar simulators, validating experimental setups, and benchmarking performance deviations in test modules. The results indicate that when two protective lenses are implemented in their normal (aligned) orientations, their effect on the reference cell is identical to having no cover at all.

Keywords: photovoltaic cells, protective lenses, experimental results, Calibrating solar simulators, and I-V and P-V curve characteristics.
