Tapered stereo-shaped array solar cell power generation system

Abstract

A tapered stereo-shaped array solar cell power generation system comprises: several cones, which are arranged in an array type on a base and possess stereo cones formed by at least more than three surfaces of panels, wherein the each cone of the cones is formed by small cone angles and there are several groups; several solar cells, which are arranged on the surfaces of the cones, wherein the solar cells with different materials are respectively arranged on the two panels which are in mutual corresponding positions of the each cone and the solar cells with the same material are arranged on the two panels which are in similar positions of the each cone. The each solar cell can convert full band of full spectrum light energy of incident ray into electric energy. The Incident sunshine can only be reflected and absorbed on the each conical surface so that incident sun light energy can be completely absorbed and be used to perform power generation. By using the system of the invention, generating efficiency of a photoelectric system can be raised; a heat dissipation area can be increased; the heat dissipation is good; photoelectric conversion efficiency can be effectively raised. The system can be used in various kinds of irregular surfaces. Manufacturing costs and time can be greatly reduced.

Description

technical field [0001] The invention relates to a conical three-dimensional array solar battery power generation system. Background technique [0002] With the progress of human life, the demand for energy is increasing rapidly. However, the energy stored in the earth is limited and is becoming exhausted. Therefore, human beings are constantly seeking and developing alternative energy sources, and solar energy is one of the alternative energy sources. Solar power generation is to use semiconductor materials to make a solar cell, which can convert light energy into electrical energy to provide electricity. [0003] A general solar cell power generation system is provided with several solar cells on a flat plate, wherein the solar cells are formed on the top surface of a substrate such as glass or silicon in sequence with a first conductive layer, a photoelectric conversion layer, a second conductive layer, An anti-reflection layer and conductive wires, so that the incident l...

Problems solved by technology

However, the interface between the first conductive layer and the photoelectric conversion layer is a plane, and before the incident light is refracted into the photoelectric conversion layer, part of the light energy will be reflected and scattered by the plane between the first conductive layer and the photoelectric conversion layer and go away. The photoelectric conversion layer, light energy is not completely absorbed by the photoelectric conversion layer, resulting in a decrease in the efficiency of the solar cell

Therefore, some operators have provided an anti-reflection material on the surface of the solar cell, but this increases the manufacturing cost and time of the solar cell panel, and because the thickness of the anti-reflection layer cannot take into account all incident sunlight wavelengths, its reflection cannot be comprehensive. Due to the characteristics of optoelectronic materials, the retained light energy can only convert part of the spectrum into electrical energy, so its efficiency is still limited.

[0004] Furthermore, the excess energy entering the solar cell that is not converted into electrical energy is either reflected or transmitted, or forms heat energy. When heat energy accumulates in the battery, it will cause the temperature of the components to rise, resulting in a decrease in the conversion efficiency of the battery.

Generally, there are two ways for solar cells to dissipate heat. One is that the solar cell directly radiates heat to the outside air through the package surface, and the other is that the package structure transfers heat to a circuit board, and then the circuit board Transfer heat to the outside air, however, when the light energy absorbed by the solar cell increases, the temperature also rises accordingly, the heat energy of the solar cell cannot be quickly transferred from the packaging surface or the circuit board to the outside air, and the solar cell The photoelectric conversion efficiency decreases with the

In addition, the concept that black body radiation can completely absorb incident light, sound waves, and electromagnetic waves has been widely used in anechoic chambers for noise testing, communication and electromagnetic interference testing, but not for solar power generators.

[0005] In addition, the substrate of the solar panel is a hard plate with a certain volume, which cannot cover and assemble on a non-planar surface, so its arrangement and position are limited. Depending on the intensity of the incident sunlight and the efficiency of power generation, some power generation systems will be equipped with solar tracking control devices. However, this method will consume some electricity in addition to increasing the cost of installation and maintenance.
