Three-in-one solar module
Technical field
The utility model relates to area of solar cell, especially relates to the three-in-one solar module of monocrystalline silicon, polysilicon and amorphous silicon.
Background technology
In the prior art, the photoelectric conversion efficiency of monocrystaline silicon solar cell is about 17%, and the highest reaches 24%; This is that photoelectric conversion efficiency is the highest in the solar cell of present all kinds, but cost of manufacture is higher, and the polysilicon solar battery slice photoelectric conversion efficiency is relatively low; But cost of manufacture is lower, and solar battery sheet has the good and poor of low light level effect; Promptly under low light condition, its photoelectric conversion efficiency has height, if; The simple solar module that adopts the solar battery sheet of low light level effect difference is difficult to satisfy the specific (special) requirements in certain some occasion, like some high light and the low light level all than the area of growing.Amorphous silicon solar cell is the novel thin membrane type solar cell that occurs in 1976; It is different fully with the manufacture method of monocrystalline silicon and polycrystalline silicon solar cell, and technical process is simplified greatly, and silicon materials consumption seldom; Power consumption is lower, and its major advantage is also can generate electricity at low light condition.But the subject matter that amorphous silicon solar cell exists is that photoelectric conversion efficiency is on the low side, and international most advanced level is about 10% at present, and stable inadequately, along with the prolongation of time, and its conversion efficiency decay.
The utility model has carried out useful improvement in order to overcome above-mentioned defective.
The utility model content
The purpose of the utility model is to solve above-mentioned deficiency of the prior art, and a kind of three-in-one solar module is provided.
To achieve these goals, the utility model adopts following technical scheme:
Three-in-one solar module; Its special character is: comprise first group of solar battery sheet, second group of solar battery sheet, the 3rd group of solar battery sheet and laminate; Said first group of solar battery sheet is the monocrystaline silicon solar cell sheet; Said second group of solar battery sheet is polysilicon solar battery slice, and said the 3rd group of solar battery sheet is the non-crystal silicon solar cell sheet, and first group of solar battery sheet is provided with first output port; Second group of solar battery sheet is provided with second output port, and the 3rd group of solar battery sheet is provided with the 3rd output port;
Further, said first group of solar battery sheet, said second group of solar battery sheet and the 3rd group of solar battery sheet are arranged respectively, form at least three row solar battery sheets;
Further, said laminate comprises backsheet layer and cover-plate glass layer, and said laminate plays the effect of support, load-bearing, protection and sealing to said first group of solar battery sheet, second group of solar battery sheet and the 3rd group of solar battery sheet;
Further, said first output port, second output port and the 3rd output port are connected with external cable respectively;
The beneficial effect of the utility model: the utility model is simple in structure; It is easy for installation through three groups of solar battery sheets are set in solar module; Thereby satisfied the application of solar module under different high lights and low light condition, and guaranteed its photoelectric conversion efficiency.
