Solar panel capable of improving electric energy conversion rate

Abstract

The invention relates to a solar panel capable of improving the electric energy conversion rate. A glass layer, a first packaging layer, a solar cell layer, a second packaging layer and a back plate layer are sequentially stacked and assembled on the solar panel from the front face to the back face. A conductive layer is combined on the front surface or the back surface of the second packaging layer; therefore, the plurality of conductive powder arranged in the conductive layer can block and absorb photoelectromagnetic waves which are not fully absorbed by the solar cell, and then reflect thephotoelectromagnetic waves to the solar cell for use so as to convert the photoelectromagnetic waves into electric energy for output, so the efficiency of absorbing and converting sunlight into electric energy by the solar panel can be greatly improved.

Description

technical field [0001] The present invention relates to a solar panel that can improve the conversion rate of electric energy, especially a solar panel that can block and completely absorb the light and electromagnetic waves that are not fully absorbed by solar cells, and then provide them to the solar cells for continuous conversion into electrical energy . Background technique [0002] With the development of modern industry and society, human beings are increasingly dependent on energy. With the depletion of traditional energy such as crude oil, coal and natural gas and the rising awareness of environmental protection, various alternative energy solutions such as wind power, hydropower and solar power generation have been valued by countries all over the world. [0003] Among them, solar power generation is the most widely used alternative energy source in the world today. The main reason is that solar energy is inexhaustible and inexhaustible, and the radiant energy pro...

Problems solved by technology

Existing solar power generation mainly uses multiple solar cells installed on the solar panel to convert sunlight into electrical energy and then output it. Due to the design of the existing solar cells, the absorption efficiency of light and electromagnetic waves with a wavelength of 0.2 μm to 0.4 μm in sunlight is better. The absorption efficiency of photoelectromagnetic waves of other wavelengths is relatively poor, so when photoelectromagnetic waves of other wavelengths pass through the solar cell, they often penetrate and emit from the bottom side of the solar panel before being fully absorbed by the solar cell and converted into electrical energy, resulting in a large Detract from the photoelectric conversion efficiency of existing solar panels

Furthermore, when solar cells convert photoelectric waves into electrical energy, heat energy will be generated at the same time. Since the existing solar panels do not have a cooling device design, if the heat energy cannot be effectively dissipated, the solar panels will reduce their power generation efficiency due to overheating
