Abstract
The invention relates to a concentrating solar cell, and belongs to the technical field of solar power generation. The concentrating solar cell comprises negative electrode layers, a concentrating solar cell substrate layer, a positive electrode layer and the effective area, wherein one surface of the concentrating solar cell substrate layer is covered with the positive electrode layer, the negative electrode layers are arranged on the other surface of the concentrating solar cell substrate layer in a covering mode, and the part between the two negative electrodes is the effective area. According to the concentrating solar cell, under the condition that the condensation times is larger than one thousand, and the geographical condition that light is strong, it can be ensured that high current can be smoothly guided out through a positive electrode and the negative electrodes without damaging the cell, and focal spots converged through a Fresnel lens can converge on the effective area of the concentrating solar cell in a certain time quantum in a complete superposition mode; a motor of a solar energy tracker can only work one time in a set time quantum, and therefore the power supply power for the motor is greatly reduced, and more energy is saved.
Description
Technical field
The present invention relates to a kind of photovoltaic generation parts, be specifically related to a kind of concentrating solar battery sheet, belong to solar energy generation technology field.
Background technology
Conventionally, the principal benefits that high power concentrating photovoltaic photoelectric conversion receiver is looked for is the high density solar radiation light that obtains converging from Fresnel Lenses on the effective area of concentrating solar battery chip.The multiple of lens is higher, and the density that obtains solar radiation light is higher, and the condensation photovoltaic battery chip using in equal area is fewer, and the cost of electricity-generating in unit are is just lower.
Conventionally the focal spot converging from Fresnel Lenses is at present all square, the shape of the shape of this focal spot and big or small also common and concentrating solar battery sheet and in the same size, thus the focal spot that Fresnel Lenses converges is converged on concentrating solar battery sheet completely.But in actual applications, the sun is at any time mobile, will causes like this focal spot that converges from Fresnel Lenses after the time period can be not completely and the coincidence of the effective area of concentrating solar battery sheet, thereby cause the reduction of conversion efficiency; If while concentrating solar battery sheet is at every moment all followed the sun and is moved, just will inevitably allow tracker at every moment all follow the sun and move, will drive with a lot of electricity the machine operation of tracker like this.
Summary of the invention
The object of this invention is to provide a kind of 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 concentrating solar battery sheet, it is characterized in that, and it comprises positive electrode layer, concentrating solar battery substrate layer, positive electrode layer and effective area.Described concentrating solar battery substrate layer is simultaneously positive electrode layer, and another side is positive electrode layer, and the part in the middle of two negative electrodes is effective area.
Described concentrating solar battery substrate layer is that GaInP/GaAs/Ge three-layered node is fit.
Described positive electrode layer area shape and concentrating solar battery substrate layer area shape are just the same.
Described positive electrode layer has the electrode layer of two equal area shapes, and the symmetrical opposite end surface that is placed on concentrating solar battery substrate layer.
The width of described each positive electrode layer is 0.5 ~ 1.5mm, and thickness is 0.2 ~ 1mm.
Described effective area is a rectangular shape, and long and wide difference is between 0.01 ~ 1mm.
Advantage of the present invention and good effect are: 1. width is that the negative electrode that 0.5 ~ 1.5mm and thickness are 0.2 ~ 1mm can bear the rated current that surpasses 10 ~ 50 amperes; 2.The focal spot converging from Fresnel Lenses can all overlap completely and converge in the effective area of concentrating solar battery sheet in certain hour section; 3. set the machine operation of a time period solar tracking device once, so just greatly reduced the output power to motor, thus more energy-conservation.

Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
A kind of concentrating solar battery sheet, as shown in Figures 1 to 3, concentrating solar battery substrate layer 2 one sides are covered with positive electrode layer 3, another side is covered with positive electrode layer 1, part in the middle of negative electrode is the effective area 4 of concentrating solar battery sheet, wherein the length of effective area 4 is A, and the wide of effective area 4 is B, and long and wide difference is between 0.01 ~ 1mm.
Concentrating solar battery substrate layer 2 combines positive electrode 3 and negative electrode 1 dexterously by special process, can guarantee that large electric current guides by positive electrode 3 and negative electrode 1 very swimmingly, also can guarantee that each electrode and connecting line can bear the rated current of 10 ~ 50 amperes simultaneously.
On concentrating solar battery substrate layer 2, process negative electrode 1, the width of negative electrode 1 is 0.5 ~ 1.5mm, and thickness is 0.2 ~ 1mm, is convenient to the smooth conducting of large electric current.
Concrete operations are as follows: first the long limit of concentrating solar battery sheet effective area is kept to consistent with east-west direction, when the sun moves a period of time during section from east to west, can guarantee that the sunlight focal spot converging from Fresnel Lenses converges to the effective area of concentrating solar battery sheet completely.
In the present invention, as becoming row embodiment, the length of effective area and wide can exchange are set making, and the positive and negative electrode of concentrating solar battery sheet also can exchange to set and make.Therefore the scope that the scope of the present invention limits with claims is as the criterion.
