Problems solved by technology

However, the processing technology for making Fresnel lenses is relatively difficult, and the cost of investment is relatively high, especially the larger the light-receiving area, the more difficult the processing (mainly the production of die-casting molds and plastic processing), and it is made of quality Made of soft plastic materials, it is difficult to protect under poor environmental conditions, and generally has a short lifespan, which is not conducive to large-scale promotion
It is easier to make multi-faceted reflectors to concentrate light, but the enhanced light-gathering efficiency it can enhance is relatively limited

Embodiment 1-2

[0061] The difference between the high-efficiency solar photovoltaic cell concentrating device provided in this embodiment and Embodiment 1-1 is that: the number of the concentrating units is multiple, the optical axes of each concentrating unit are parallel to each other, and the plurality of concentrating units The sub-reflectors 2 are pasted at different positions on the rear side of the same transparent optical glass plate.

[0062] Such as Figure 7 and Figure 8 Shown are 9 identical light-gathering units designed in the above-mentioned embodiment 1-1 at 1m 2 Schematic diagram of the combined optics of the whole machine. The optical axes of each concentrating system need to be adjusted to be parallel to each other. Due to the use of a unified protective glass, the more complex processing of mechanical parts for fixing is avoided, and the production cost can be reduced.

Embodiment 2-1

[0064] The mirror surface of the main reflector 1 is preferably a cylindrical paraboloid or a quadric surface or a spherical surface, and the mirror surface of the secondary reflector 2 is preferably a cylindrical paraboloid or a quadric surface or a spherical surface. The central axes of the cylinders of the reflector 2 are parallel to each other; the focal plane of the Cassegrain type telescopic concentrator system is located between the primary reflector 1 and the secondary reflector 2; the light-receiving surface of the solar photovoltaic cell device 3 is located on the card Between the focal plane of the Segren type telescopic concentrating combination system and the main reflector 1; the solar photovoltaic cell device 3 is composed of two or more light-receiving areas with large (generally greater than 30×30mm), low photoelectric conversion efficiency and durability. Solar photovoltaic cells with poor thermal performance are arranged along a direction parallel to the cent...
