Abstract
The invention relates to an efficient concentration solar cell, and belongs to the technical field of solar power generation. The efficient concentration solar cell comprises two rows of negative electrode section layers, a concentration solar cell base material layer and a positive electrode layer. The concentration solar cell base material layer enables the positive electrode layer and the two rows of I-shaped negative electrode section layers to be ingeniously combined together through a special technology. According to the efficient concentration solar cell, a photovoltaic system enables four or more concentration solar cells to be tightly arrayed together directly, namely, the four or more concentration solar cells are welded at a time to form a concentration solar photovoltaic conversion receiver; meanwhile, the concentration solar photovoltaic conversion receiver which is formed by the four or more concentration solar cells can be radiated by a radiator, working strength is greatly reduced, working time is greatly shortened, and thus working efficiency can be improved; in addition, due to the shape and the design of the negative electrode section layers of the solar cell, the light absorption area is effectively increased, and the conversion efficiency of the concentration solar cell can be overall improved.
Description
Technical field
The present invention relates to a kind of photovoltaic generation parts, be specifically related to a kind of high-efficiency concentration solar battery, belong to solar energy generation technology field.
Background technology
Usually, the principal benefits sought by high concentration solar photoelectric conversion receiver is the high density solar radiation light obtaining converging from Fresnel Lenses on the effective area of concentrating solar battery.The multiple of lens is with height, and the density obtaining solar radiation light is higher, and the concentrating solar battery that equal area uses is fewer, and the cost of electricity-generating in unit are is lower.
Along with the increase of lens multiple, the light energy converged on concentrating solar battery is larger, and fraction light energy is converted into electric energy, and most of light energy is converted to heat energy.Photospot solar systems all is at present all load a radiator according to a concentrating solar battery back side, will cause the working strength of a large amount of installation of heat radiators and welding concentrating solar battery like this, thus increase the manufacture processing cost of product.
Summary of the invention
The object of this invention is to provide a kind of high-efficiency concentration solar battery, this battery is to overcome the deficiencies in the prior art.
In order to realize above-mentioned technical purpose, the technical scheme that the present invention takes is: a kind of high-efficiency concentration solar battery, it is characterized in that, it comprises two row's negative electrode section layers, concentrating solar battery substrate layer and positive electrode layer, described concentrating solar battery substrate layer one side is positive electrode layer, and another side is two row's negative electrode section layers.
Described concentrating solar battery substrate layer is that GalnP/GaAs/Ge three-layered node is fit.
Described positive electrode layer area shape and concentrating solar battery substrate layer area shape just the same.
Described often row negative electrode section layer is multiple I shape negative electrode section layers, and two row's negative electrode section layers are placed on any two adjacent faces of concentrating solar battery substrate layer.
The width of described each negative electrode section layer is 0.5 ~ 1. 5mm, and length is 1 ~ 5mm, and thickness is 0.2 ~ 1mm.
Advantage of the present invention with good effect is: 1. can directly by together with the concentrating solar battery close-packed arrays of more than four or four, and namely the disposable concentrating solar battery to more than four or four carries out welding processing is condensing solar opto-electronic conversion receiver; 2. a radiator can dispel the heat to the condensing solar opto-electronic conversion receiver of the concentrating solar battery formation of more than four or four simultaneously, greatly reduces working strength and operating time, thus increases work efficiency; 3. the shape of the negative electrode section layer of this cell piece and design increase effectively light-receiving area, the conversion efficiency of concentrating solar battery sheet entirety can be improved.
