Problems solved by technology

The best receiving angle of traditional solar receivers is about 7 degrees, beyond the best area, there is high-speed fading, so the photoelectric conversion efficiency is reduced to about 17%
[0004] In the prior art, a better receiving angle is obtained through the sun tracking system based on the mechanical principle, but this method is expensive and the recovery rate of the cost-benefit ratio is low

Embodiment 1

[0034] figure 1 A structural schematic diagram of a solar power generation device provided by an embodiment of the present invention, such as figure 1 As shown, the solar power generation device includes a solar cell panel 101 and a bull's-eye structured grating 102, and the bull's-eye structured grating 102 covers the upper surface of the solar cell panel 101; the surface of the bull's-eye structured grating 102 is engraved with periodic annular slits, And formed a periodic grating structure.

[0035] When the light encounters the grating, the propagation direction of the light will change to varying degrees, that is, the phenomenon of diffraction. Diffraction is closely related to the material and constant of the grating, both of which can change the deflection angle and intensity of light. Wherein, the grating constant p=slit width a+slit spacing b. Through reasonable adjustment of the grating constant (structural size), the bull's-eye structured grating 102 can achieve ...

Abstract

The invention provides a solar power generation device and a vehicle, and relates to the technical field of energy. The solar power generation device comprises a solar cell panel and a bull's eye structure grating, wherein the bull's eye structure grating covers the upper surface of the solar cell panel, and the surface of the bull's eye structure grating is provided with periodic annular slits inan engraved manner and a periodic grating structure is formed. Since the grating can change the propagation direction of the incident light, the solar power generation device can expand the receivingangle of the spatial light by diffraction of the grating, and the special design of the grating structure of the bull's eye structure grating enables the receiving angle of the spatial light to be larger in angle spectrum. Compared with a conventional sun tracking system, the device greatly reduces the cost.

Description

technical field [0001] The invention relates to the field of energy technology, in particular to a solar power generation device and a vehicle. Background technique [0002] The principle of solar energy application is to use space light (sunlight, artificial light, cosmic rays, etc.) radiation energy to form a pattern excitation with a solar receiver device, and convert light energy into electrical energy through photoelectric conversion. In recent years, solar cell technology has developed rapidly, and the use scenarios are becoming more and more abundant. Solar cells, also known as "solar chips" or "photovoltaic cells", are photoelectric semiconductor sheets that use sunlight to generate electricity directly. As long as it is illuminated by light that meets certain illumination conditions, it can output voltage instantly and generate current when there is a loop. [0003] Due to the limited receiving angle of space light and problems such as photoelectric conversion eff...
