Parametric Study of Solar Concentrator Composed of a Flat Fresnel Lens and a Reflective Secondary Optical Element
Abstract
This study presents a parametric design process of a solar concentrator for high concentrated photovoltaic (HCPV) system. The concentrator comprises a flat Fresnel lens and a reflective secondary optical element (SOE). Ray tracing simulation is utilized to explore the optical performance of the concentrator under various design parameters. The optical performance of the solar concentrator, including the optical efficiency, acceptance angle and irradiance distribution, is evaluated via parametric study to achieve an optimum design. Finally, the achieved design of the solar concentrator for HCPV exhibits a high optical concentration ratio (OCR) of 909X, and an acceptance angle of 1.03o.
