Problems solved by technology

However, from a technical point of view, the uniformity of the concentrated light intensity of the Fresnel lens on a specific surface is relatively poor.
From an industrial point of view, compared to reflective methods, the cost of special lenses is still higher than the cost of reflective mirrors with high reflectivity

Embodiment Construction

[0021] Such as figure 1 As shown, the photovoltaic cell 4 is conductively connected by the corresponding conductive wire 5, and is fixed on the radiator substrate 6 through the adhesive film 3, and the photovoltaic cell 4, the conductive wire 5 and the radiator substrate 6 are insulated by the adhesive film 3 . More than one group of photovoltaic cells 4 can be mounted on one heat sink substrate 6 , and together with the conductive wires 5 constitute an electrical energy exporter. More than one set of reflective surfaces 11 are arranged on the reflective support body 2, and the bottom of each reflective surface 11 corresponds to a photovoltaic cell 4, and the opening above the reflective support body 2 is fixed and covered by a transparent protective cover plate 1. Made of hardened or tempered glass with high light transmittance, or made of optical plastic, it is required to have waterproof, dustproof and considerable impact resistance functions to adapt to various outdoor ha...

Abstract

The invention discloses a double inclined plane reflecting condensation solar photovoltaic battery module which is composed of a framework, a transparent protective cover board, a reflecting support body, photovoltaic batteries, an electric conduction line and a radiator base plate; more than one groups of reflecting surfaces are arranged on the reflecting support body, and the bottom part of each reflecting surface corresponds to one photovoltaic battery; the reflecting surface is composed of two trapezoids which are arranged symmetrically, and the short bottom sides of the two trapezoids form a rectangle where the photovoltaic batteries are arranged, and the long bottom sides of the two trapezoids form a rectangle which is a sunlight incidence window. Under a tracking condition, light rays reflected by the reflecting surfaces can be covered to each point of the photovoltaic batteries all year round. The surface of each photovoltaic battery can receive solar direction radiation and superposition radiation formed by reflection of the reflecting surface, so as to form light condensation effect on the photovoltaic battery, improve photoelectricity conversion efficiency of unit area, achieve the purpose of using less photovoltaic batteries under a given power condition and reduce the total cost of the photovoltaic power-generating system.

Description

technical field [0001] The invention relates to a structure of a photoelectric conversion module of a concentrating photovoltaic system, which belongs to the technical field of solar energy utilization, in particular to a double-slope reflective concentrating solar photovoltaic cell assembly. Background technique [0002] The development of new energy and renewable clean energy is a common issue faced by the whole world. In the development and utilization of new energy, photovoltaic power generation has attracted much attention. At present, photovoltaic power generation mainly adopts ordinary flat-panel photovoltaic power generation system. Ordinary flat-panel photovoltaic power generation systems directly place flat-panel solar cell components towards low-latitude regions (at a certain angle to the ground), and form solar photovoltaic arrays in series and parallel to achieve the purpose of using solar power to generate electricity. In an ordinary flat-panel photovoltaic po...
