摘要

This paper proposes and analyzes an improved hybrid system combining a CPC and a PTC. The new system enhances PV module conversion efficiency by shifting the parabolic trough concentrator's focus from a TEG module to a PV module, utilizing PV waste heat for improved overall energy efficiency. The previous system with TEG achieved a PV output of 39.27 W and TEG output of 6.63 W under 998 W/m2 light intensity, while the improved system achieved a 23.8% efficiency increase, reaching 56.84 W without the TEG. Simulation and modeling results show effective thermal management and energy efficiency optimization under varying light intensity and ambient temperatures. This design provides a practical pathway for optimizing future solar energy systems. The proposed hybrid CPC-PTC system addresses the efficiency limitations of traditional photovoltaic systems by combining the advantages of both concentrators. The motivation for this study is to enhance solar energy utilization by improving the optical and thermal performance of PV modules. This research optimizes concentrator configuration to maximize energy absorption and achieve higher conversion efficiency. The methodology includes geometric modeling with Solidworks, optical simulation using TracePro, and thermodynamic analysis with EES. The results demonstrate significant improvements in PV efficiency and thermal management, highlighting the potential of this hybrid system for renewable energy applications.
