Problems solved by technology

[0004] Existing solar panels generally need to be exposed outdoors. For a long time, their light-collecting surfaces are easily polluted, resulting in a decrease in light transmittance, a decrease in photoelectric conversion efficiency under the same light radiation conditions, and sometimes a "hot spot" effect. Its components are fatally damaged, which affects its normal use, so manual cleaning is usually required, which is time-consuming and sometimes cannot be cleaned in time

Embodiment Construction

[0010] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0011] see figure 1 , the solar panel 100 provided by the embodiment of the present invention includes: a glass plate 11 , a solar cell group 12 and a plurality of ultraviolet light emitting diodes 13 .

[0012] The glass plate 11 includes a light collecting surface 11a, a bottom surface 11b opposite to the light collecting surface 11a, and a side surface 11c located between the light collecting surface 11a and the bottom surface 11b. A photocatalyst layer 14 is disposed on the light collecting surface 11 a of the glass plate 11 . The solar cell group 12 is opposite to the bottom surface 11 b of the glass plate 11 . The glass plate 11 is preferably quartz glass with high UV light transmittance. The photocatalyst layer 14 generally selects titanium dioxide (TiO 2 ), titanium dioxide absorbs light with a wavelength less than or equal to 3...

Abstract

The invention relates to a solar panel, comprising a glass board, a solar battery and at least one ultravoilet light-emitting diode. The glass board includes a light collecting surface, a bottom surface opposite to the light collecting surface and a lateral surface between the light collecting surface and the bottom surface; the light collecting surface is provided with a photocatalyst layer,; the solar battery is opposite to the bottom surface; and the at least one ultravoilet light-emitting diode is opposite to the lateral surface of the glass board, and the ultravoilet light emitted therefrom goes through the lateral surface of the glass board and irradiates on the photocatalyst layer.

Description

technical field [0001] The invention relates to a solar panel. Background technique [0002] Solar panels have become a research hotspot in the field of energy. They can be applied to buildings such as houses, devices such as street lighting, and even various portable electronic devices to convert sunlight energy into electrical energy. [0003] Solar panels use solar panels to convert the sun's radiant energy photons into electrical energy through semiconductor materials (see "Grown junction GaAs solar cell", C.C.Shen; Pearson, G.L.; Proceedings of theIEEE, Volume 64, Issue 3, March 1976 Page( s): 384-385). [0004] Existing solar panels generally need to be exposed outdoors. For a long time, their light-collecting surfaces are easily polluted, resulting in a decrease in light transmittance, a decrease in photoelectric conversion efficiency under the same light radiation conditions, and sometimes a "hot spot" effect. Its components are fatally damaged, which affects its n...
