Abstract
The invention relates to a high-efficiency concentrating solar battery piece and belongs to the technical field of solar power generation. The high-efficiency concentrating solar battery piece comprises a plurality of negative electrode section layers, a concentrating solar battery base material layer, a positive electrode layer and an active area part, wherein the positive electrode layer is arranged on one surface of the concentrating solar battery base material layer, the negative electrode section layers are arranged on the other surface of the concentrating solar battery base material layer, and the part except a negative electrode is the active area part. According to the battery piece, a large current can be smoothly led out through the positive electrode layer and the negative electrode section layers without damaging the battery piece under the geographical conditions that the concentrating multiple is larger than 1000 and light is very strong; in the machining process, the probability of damage to the battery piece is decreased, and therefore the production yield is increased. Meanwhile, due to the shape and the design of the I-shaped negative electrode section layers of a battery chip, the light receiving area is effectively enlarged, and the conversion efficiency of the battery chip can be improved; focal spots concentrated from a Fresnel lens can be completely concentrated in the effective area part of the concentrating solar battery piece in an overlapped mode in a certain period of time. A motor of a solar tracker works one time in a set period of time, so that power supply power provided for the motor is greatly reduced, and accordingly 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 high efficiency condensing 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 sheet.The multiple of lens is higher, and the density that obtains solar radiation light is higher, and the concentrating solar battery sheet 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 high efficiency condensing 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 high efficiency condensing solar battery sheet, it is characterized in that, it comprises a plurality of negative electrode section layers, concentrating solar battery substrate layer, positive electrode layer and effective area, described concentrating solar battery substrate layer is simultaneously positive electrode layer, another side is a plurality of negative electrode section layers, and the part outside negative electrode 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 is a plurality of negative electrode section of I shape layer, and is placed on one of them end face of concentrating solar battery substrate layer.
The width of described each negative electrode section layer is 0.5 ~ 2.5mm, and length is 1.5 ~ 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 0.5 ~ 2.5mm, and length is that the negative electrode section layer that 1.5 ~ 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; 4. this cell piece, in the course of processing, subtracts and is a half routing technique, reduces the damage of concentrating photovoltaic cell slice, thereby improve, produces yield.
