Description
Technical field
The present invention relates to a kind of photovoltaic generation parts, be specifically related to a kind of large electric current concentrating photovoltaic cell slice, belong to the solar energy generation technology field.
Background technology
Usually, the principal benefits looked for of high power concentrating photovoltaic photoelectric conversion receiver is that effective area at concentrating photovoltaic cell slice obtains the high density solar radiation light that converges from Fresnel Lenses.The multiple of lens is higher, and the density that obtains solar radiation light is higher, and the concentrating photovoltaic cell slice that uses on the equal area is fewer, and the cost of electricity-generating on the unit are is just lower.
Along with the increase of lens multiple, the light intensity that converges on the concentrating photovoltaic cell slice is just larger, and the electric current that converts on the concentrating photovoltaic cell slice is just larger.At present all concentrating photovoltaic cell slices all are to be 1000W/m according to light intensity
2Normal temperature under test with volume production, its negative electrode width is all in 0.5mm, therefore its rated current is relatively little, in large light concentrating times with the negative electrode that easily fuses under the strong condition of high light very much.Simultaneously, add man-hour in the welding of battery surface both sides or binding, the end of a thread that surpasses the connecting line of 200um can enter in the effective area of concentrating photovoltaic cell slice, if and the relative area of condensation photovoltaic negative electrode is larger, the condensation photovoltaic light-receiving area will be less, will greatly reduce like this conversion efficiency of concentrating photovoltaic cell slice.
Summary of the invention
The purpose of this invention is to provide a kind of large electric current concentrating photovoltaic cell slice, 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 large electric current concentrating photovoltaic cell slice, it is characterized in that, and it comprises a plurality of negative electrode section layers, condensation photovoltaic cell base layer and positive electrode layer.Described condensation photovoltaic cell base is laminated to be positive electrode layer, and another side is a plurality of negative electrode section layers.
Described condensation photovoltaic cell base layer is that the GaInP/GaAs/Ge three-layered node is fit.
The long-pending shape of described positive electrode layer area shape and condensation photovoltaic cell base aspect is just the same.
Described positive electrode layer is a plurality of negative electrode section of I shape layer, and is placed on any three end faces of condensation photovoltaic cell base layer.
The width of described each negative electrode section layer is 0.5 ~ 1.5mm, and length is 1.5 ~ 5mm, and thickness is 0.2 ~ 1mm.
Advantage of the present invention and good effect are: 1. width is 0.5 ~ 1.5mm, and length is that 1.5 ~ 5mm and thickness are that the negative electrode section layer of 0.2 ~ 1mm can bear and surpasses 10 ~ 50 amperes rated current; 2.Add man-hour in welding or binding, can guarantee that 1mm can not enter in the effective area of concentrating photovoltaic cell slice with connecting line the end of a thread of interior wire diameter; 3. the shape of the negative electrode section layer of this cell piece has effectively increased relative light-receiving area with design, can be with the whole raising of the conversion efficiency of concentrating photovoltaic cell slice.
