Concentrated Photovoltaic System with Multi-Curvature Fresnel Concentrator
A multi-curvature Fresnel concentrator is proposed in this study for a concentrated photovoltaic system (CPV) to suppress aberrations. Unlike a conventional Fresnel concentrator with a single curvature, the proposed one integrates several Fresnel concentrators with individual curvatures. An embodiment is designed for a PMMA concentrator comprising four curvatures. The simulated efficiency of the embodiment is 86.4%. The tolerance analyses and the fabrication considerations of the CPV are provided and discussed.
