Design and Fabrication of Concentrated Photovoltaics

Abstract

To mark the corresponding low Efficiency of Photovoltaic (PV) systems, a unique concentrator was developed to strengthen the intensity of solar irradiance falling on the surface of PV, therefore upgrading its power output. A best design for a Concentrated Photovoltaic (CPV) system was visualize and constructed, featuring a workable concentration mechanism that authorizes the adjustment or complete removal of the concentrator depend on operational requirements. Comprehensive experimental evaluations were performed on this system. Results presented that by using a low-level concentrator led to an increase of 39.85% under clear-sky environments, while its performance decreases under rainy or cloudy weather due to the dependency on direct sunlight. Important challenges just like optical misalignment, thermal buildup, and lowered performance under diffuse light were investigated, and practical techniques to reduce these problems were discussed. The results showed both the abilities and the limitations of low-concentration CPV systems in the region with variable irradiance, providing insights for future optimization through advanced thermal management, optical design, and adaptive tracking techniques.
