Abstract

The cost of photovoltaic power generation can be saved and efficiency will be improved by the concentration optics system. However, the non-uniformity of illumination distribution on the photovoltaic cells of the current Fresnel concentrators will reduce the photoelectric conversion efficiency and decrease the service life of the cell even damage the cell. This paper presents the design and simulation a novel nonimaging Fresnel concentrator, then comparatively analyses the performances of the conventional Fresnel concentrator. The novel nonimaging Fresnel concentrator has been design according to the diffused focal points method to improve optical efficiency and illumination uniformity. The novel Fresnel concentrator achieves high concentration efficiency 82.20%, and high uniformity 89.23% in the scope ±4mm of the concentration spot which can improve photoelectric conversion efficiency of photovoltaic cells and prevent the photovoltaic cells from being damaged.
