The high-current-resistant concentrating photovoltaic cell piece comprises a negative electrode layer, a concentrating photovoltaic cell base material layer and a positive electrode layer, wherein the concentrating photovoltaic cell base material layer ingeniously combines the positive electrode and the negative electrode through a special process. The high-current-resistant concentrating photovoltaic cell piece has the advantages that under the regional conditions of concentrating multiple of over 1,000 and strong light, high current can be smoothly led out through the positive electrode and the negative electrode, and the cell piece is not damaged.
Description
Technical field
The present invention relates to a kind of photovoltaic generation parts, be specifically related to a kind of anti-big electric current condensation photovoltaic battery sheet, belong to the solar energy generation technology field.
Background technology
Usually, the principal benefits looked for of high power concentrator photovoltaic opto-electronic conversion receiver is on the effective area of condensation photovoltaic battery chip, to obtain the high density solar radiation light that converges from Fresnel Lenses.The multiple of lens is high more, and the density that obtains solar radiation light is high more, and the condensation photovoltaic battery chip that uses on the equal area is few more, and the cost of electricity-generating on the unit are is just low more.
Along with the increase of lens multiple, the light intensity that converges on the condensation photovoltaic battery sheet is just big more, and the electric current that conversion is come out on the condensation photovoltaic battery sheet is just big more.At present all condensation photovoltaic battery sheets 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, so that its rated current compares is less, negative electrode easily fuses under big light concentrating times and the strong condition of high light very.Simultaneously, welding or binding add man-hour on the battery surface both sides, and the end of a thread that surpasses the connecting line of 200um can enter in the effective area of condensation photovoltaic battery sheet, will reduce the conversion efficiency of condensation photovoltaic battery sheet so greatly.
Summary of the invention
The purpose of this invention is to provide a kind of anti-big electric current condensation photovoltaic battery sheet, this battery sheet is to overcome the deficiency of prior art.
In order to realize above-mentioned technical purpose, the technical scheme that the present invention takes is: a kind of anti-big electric current condensation photovoltaic battery sheet is characterized in that it comprises positive electrode layer, condensation photovoltaic cell base layer and positive electrode layer.Said condensation photovoltaic cell base is laminated to be positive electrode layer, and another side is a negative electricity basic unit.
Said condensation photovoltaic cell base layer is that the GaInP/GaAs/Ge three-layered node is fit.
The long-pending shape of said positive electrode layer area shape and condensation photovoltaic cell base aspect is just the same.
Said positive electrode layer has the electrode layer of two equal area shapes, and symmetry is placed on the both ends of the surface of condensation photovoltaic cell base layer.
The width of said each positive electrode layer is 0.5 ~ 1.5mm, and thickness is 0.2 ~ 1mm.
Advantage of the present invention and good effect are: 1. width is that 0.5 ~ 1.5mm and thickness are that the negative electrode 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 condensation photovoltaic battery sheet with the connecting line the end of a thread in footpath, interior lines.
