Abstract

The invention relates to a novel solar power generation device. The device consists of a solar power generation spherical shell, a reflection condensing mirror, an inverter, a storage battery and a controller, wherein the solar power generation spherical shell is spliced by power generation module blocks and is fixed to the surface of a metal or fiber reinforced resin composite material spherical support; the outer diameter of the solar power generation spherical shell is between 100 and 100,0000 mm; the illuminated face of a power generation module is prepared from organic or inorganic material composite films which are positioned, assembled and dispersed by one or all metal nanoparticles such as nanometer graphene, carbon nanotubes, nano carbon black, cadmium compound, lead (Pb), aluminum (Al) and the like; and any surface of the solar power generation spherical shell is positioned at focal positions of reflected light rays on the inner surface of the reflection condensing mirror all the time, so that light irradiated on the surface of the condensing mirror can be reflected to the surface of the solar power generation spherical shell.

Description

technical field [0001] The invention relates to a building block spherical shell torch type solar power generation device. The building block spherical shell refers to a spherical shell composed of more than two spherical module building blocks; the torch type solar power generation device means that it is shaped like a torch. Background technique [0002] In recent years, problems such as global warming and environmental pollution caused by the extensive use of fossil fuels have become increasingly serious, and people's attention to clean energy has been strengthened. [0003] Photovoltaic power generation is to use the principle of photoelectric conversion to convert the sun's radiant light into electrical energy through semiconductor materials, without generating any pollution or waste during the power generation process. Photovoltaic power generation is the cleanest and most ideal energy source. [0004] At present, a common solar power generation device is a fixed fla...

AI Technical Summary

Problems solved by technology

However, the shortcomings of the spherical solar array are: spherical semiconductor elements are difficult to process; at the same time, the honeycomb structure of the optical concentrator is complex and has low precision. Although the reflective aluminum foil can increase the light-receiving area of ​​the semiconductor element, each spherical power generation element A large number of gaps between the solar cell array reduce the effective light-receiving area

The disadvantage of this structure is: the small spherical heat collecting element is installed on the reflector, which cannot guarantee sufficient strength, and also wastes the light-receiving area of ​​the spherical heat collecting element; at the same time, the solar water heater uses multiple concave spherical reflectors The way of tiling makes there are a lot of gaps between the spherical heat collecting elements, which greatly reduces the effective area

The disadvantage of this solar hot water tank is that it only applies to the fact that the sphere can receive sunlight throughout the day, but it ignores that the incident direction of the sunlight is also related to the amount of energy, because every time the sunlight hits the sphere Except for one point, the sphere cannot be irradiated in the direct direction, so the heat collection efficiency is not greatly improved.

The disadvantage of this technology is that although the spherical appearance structure is adopted, the solar cells are only tiled on the transparent electronic component box in the upper hemisphere, which does not increase the power generation efficiency of the solar cells

The disadvantage of this device is that although the utility model patent adopts a spherical appearance structure, the solar cells are only tiled on the transparent electronic component box in the lower hemisphere, which does not increase the power generation efficiency of the solar cells

The disadvantage of this spherical solar water heater is that it does not take into account that there will be a large part of the reflection loss when the sunlight shines on the shell, thereby reducing the heat collection efficiency, and the setting of the back sun plate of the shell is unreasonable. The problem of the incident angle of sunlight reduces the contribution of the surface design of the spherical shell to the improvement of heat collection efficiency

[0014] The above public documents only use the macroscopic structure of the spherical shell, and do not carry out the microscopic design of the spherical shell structure and the splicing angle of the modules to propose efficient and low-cost power generation measures
