Condensation photovoltaic electrification CPV die set

Abstract

The invention relates to a converging photovoltaic power generation CPV module, which comprises a Fresnel lens, converging cell slices, a heat radiator and a flat box, wherein the Fresnel lens is fixed on the flat box, and is covered with a toughened glass protective layer; the converging cell slices are fixed under the flat box, and are corresponding to the focus of the Fresnel lens; moreover, the converging cell slices are connected in series or in parallel, and are fixed with the heat radiator on the edge of the converging cell slices; and the CPV module is fixed with a two-dimensional fully-automatic sun tracker. The CPV module is characterized in that a light guiding funnel is arranged between the Fresnel lens and the converging cell slices; and the lower part of the light guiding funnel is fixed with part of a secondary lens. The converging photovoltaic power generation CPV module has the advantages that the CPV module improves power generation efficiency and reduces power generation cost.

[0003] At present, in the case of large demand for monocrystalline silicon and polycrystalline silicon in the international market, high prices and low conversion rates, experts at home and abroad are looking for better solar energy conversion methods, but low-power concentrating efficiency is low, and low-power concentrating power generation High cost affects the promotion and application of solar photovoltaic power generation

Patent No. 200620081017.5 "A Non-Tracking Solar Concentrating Photovoltaic Power Generation Module" utility model patent discloses a structure of low-magnification concentrating power generation components, but the curved reflective sheet of this structure cannot completely transmit the Fresnel lens The light on the concentrating cell is in a focus shape, and part of the light is still in a scattered state, and the structure does not rotate and track with the sunlight, and the sunlight cannot always directly shine on the Fresnel lens, thereby reducing the use efficiency of light and low power generation efficiency

High-power concentrating power generation is being researched by all countries in the world. It has the characteristics of high solar conversion efficiency and low power generation cost, but there is no product for practical application. Therefore, it is imperative to speed up the research on the practical application of CPV modules for concentrating photovoltaic power generation.
