Abstract
The invention relates to a large-current concentrating solar cell chip and belongs to the technical field of solar power generation. The large-current concentrating solar cell chip comprises multiple negative electrode section layers, a concentrating solar battery base material layer and a positive electrode layer, wherein the concentrating solar battery base material layer enables the positive electrode layer and the negative electrode section layers to be combined ingeniously through a special process. According to the large-current concentrating solar cell chip, on the regional conditions of over 1000 times of condensation and strong light rays, it can be guaranteed that a large current smoothly passes through the positive electrode layer and the negative electrode section layers to be led out without damaging the cell chip; meanwhile, the shape and design of the I-shaped negative electrode section layers of the cell chip effectively enlarge the relative light receiving area, and therefore the purpose of improving the conversion efficiency of the cell chip is achieved.
Description
Technical field
The present invention relates to a kind of photovoltaic generation parts, be specifically related to a kind of big current concentrating solar battery sheet, belong to solar energy generation technology field.
Background technology
Usually, principal benefits sought by high concentration solar photoelectric conversion receiver is that the multiple of high density solar radiation light mouth lens obtaining converging from Fresnel Lenses on the effective area of concentrating solar battery sheet is higher, the density obtaining solar radiation light is higher, the concentrating solar battery sheet 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 intensity converged on concentrating solar battery sheet is larger, and the electric current that concentrating solar battery sheet converts is larger.Concentrating solar battery sheets all is at present all be 1000W/m according to light intensity
2normal temperature under carry out testing and volume production, its negative electrode width is all within 0.5mm, therefore its rated current is relatively little, easily fuse negative electrode under large light concentrating times and very strong light-intensity conditions.Simultaneously, man-hour is added in the welding of battery surface both sides or binding, can enter in the effective area of concentrating solar battery sheet more than the end of a thread of the connecting line of 200um, if and the relative area of Photospot solar negative electrode is larger, Photospot solar light-receiving area will be less, greatly will reduce the conversion efficiency of concentrating solar battery sheet like this.
Summary of the invention
Day of the present invention be to provide a kind of big current concentrating solar battery sheet, this cell piece 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 big current concentrating solar battery sheet, is characterized in that, it comprises multiple negative electrode section layer, 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 multiple 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 positive electrode layer is I shape multiple negative electrode section layer, and is placed on any three end faces of concentrating solar battery substrate layer.
The width of described each negative electrode section layer is 0.5 ~ 1. 5mm, and length is 1.5 ~ 5mm, thickness 0. 2 ~ 1mm.
Advantage of the present invention and good effect are: 1. width is 0.5 ~ 1. 5mm, and the negative electrode section layer of length to be 1.5 ~ 5mm and thickness be 0.2 ~ 1mm can bear the rated current more than l0 ~ 50 ampere; 2.Add man-hour in welding or binding, can ensure connecting line the end of a thread of wire diameter within 1mm can not enter into concentrating solar battery sheet effectively and long-pending in; 3. the shape of the negative electrode section layer of this cell piece increase effectively relative light-receiving area with design, the conversion efficiency of concentrating solar battery sheet entirety can be improved.
Accompanying drawing explanation
Fig. 1 is a kind of big current concentrating solar battery sheet front view.
Fig. 2 is a kind of big current concentrating solar battery sheet end view.
Wherein: 1, negative electrode section layer, 2, concentrating solar battery substrate layer, 3, positive electrode layer.
Specific embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
A kind of concentrating solar battery sheet, as shown in Fig. 1 ~ 2, concentrating solar battery substrate layer 2 one side is positive electrode layer 3, and another side is negative electrode section layer 1.
Positive electrode layer 3 and multiple negative electrode section layer 1 are combined by special process by concentrating solar battery substrate layer 2 dexterously, can ensure that big current moves smoothly through positive electrode layer 3 very much and negative electrode section layer 1 guides, also can ensure that each electrode layer and connecting line can bear the rated current of l0 ~ 50 ampere simultaneously.
Concentrating solar battery substrate layer 2 is processed negative electrode section layer 1, and the width of negative electrode section layer 1 is 0.5 ~ l. 5mm, and length is 1. 5 ~ 5mm, and thickness is 0.2 ~ 1mm, is convenient to the smooth conducting of big current.
Negative electrode section layer l is I shape electrode section layer, effectively can increase the relative light-receiving area of concentrating solar battery sheet.
In the present invention, 1 shape negative electrode section layer can arbitrary placement at any three end faces of battery surface, negative electrode simultaneously
The number of section layer is 6 ~ 21.
