Abstract
The utility model discloses a spliced solar monocrystalline cell slice, which belongs to the technical field of a semiconductor. The spliced solar monocrystalline cell slice comprises a monocrystalline cell slice body. The monocrystalline cell slice body is formed by splicing a first cell slice with a second cell slice. Both the first cell slice and the second cell slice have fine grid lines and main grid lines. The fine grid lines on the first cell slice are connected with the fine grid lines of the second cell slice by a brazing belt. The main grin lines on the first cell slice are connected with the main grid lines of the second cell slice by a brazing belt. Compared with the prior art, the monocrystalline cell slice body is formed by splicing two parts, and the two parts are cut from different waste cell slices, so that not only can the spliced monocrystalline cell slice be ensured to work normally, but also the waste monocrystalline cell slices are effectively utilized and resource waste is reduced.
Description
Technical field
The utility model relates to a kind of high-purity, single crystal silicon sheet.
Background technology
Surging along with whole world environmental protection consciousness, the earth are heated up, and to stay in the population power consumption demand of no electricity or power-shortage area more than 1,000,000,000 urgent day by day in the natural calamity that the caused serious day by day and whole world, will continue to grow up apace in solar cell market.At present the energy output of whole world solar cell be less than ten thousand of traditional energy energy output/, main because the cost of solar cell power generation is 2 ~ 3 times of traditional energy cost of electricity-generating.
From the solar cell photoelectric conversion efficiency, in recent years,, great breakthrough was arranged also along with improving constantly of technology level.At present, the monocrystaline silicon solar cell conversion efficiency 14% brought up to 17% before 3 years, and the polysilicon solar cell conversion efficiency also 10% brought up to 15% before 3 years, and the conversion efficiency of solar cell of Ultra-High Efficiency surpasses 50%.
Photovoltaic module output last 10 years average growth rate of last century Mo in the world's was 20%, rose to 287 megawatts in 2000 from 55 megawatts in 1991.And after entering 2000, the average growth rate per annum of global photovoltaic module is especially up to more than 30%, and the output in the whole world in 2003 has reached 744 megawatts.Photovoltaic industry becomes one of the fastest emerging industry of global evolution.Solar cell demand average growth rate per annum is up to 30%, and foreseeable rapid growth will continue more than 40 years.
But the shape of high-purity single crystal battery sheet all is quadrangle usually in the prior art, and these tetragonal four angles all are fillets, this mainly is that manufacturing process by monocrystalline silicon piece is determined, but the single crystal battery sheet damages in use and manufacture process easily, usually all be to do waste treatment for the single crystal battery sheet that has damaged now, cause significant wastage.
Summary of the invention
The utility model is at deficiency of the prior art, and a kind of simple in structure, splicing solar energy single crystal battery sheet that can effectively utilize discarded single crystal battery sheet is provided.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of splicing solar energy single crystal battery sheet, comprise single crystal battery sheet body, described single crystal battery sheet body is spliced by the first battery sheet and the second battery sheet, the described first battery sheet and the second battery sheet all have thin grid line and main grid line, thin grid line on the described first battery sheet is connected by the thin grid line of brazing band with the described second battery sheet, and the main grid line on the described first battery sheet is connected by the main grid line of brazing band with the described second battery sheet.Single crystal battery sheet body of the present utility model is spliced by two parts, and these two parts are respectively by cutting on the different waste battery sheets, can guarantee that not only spliced single crystal battery sheet normally uses, and effectively utilize discarded single crystal battery sheet, reduce the waste of resource.
In order to obtain better technique effect, further technical measures also comprise: preferred, the above-mentioned first battery sheet is identical with the shape of the described second battery sheet.Identical shaped mainly is the processing of assembly unit for convenience: when choosing the first suitable battery sheet and the second battery sheet before assembly unit, any two can be bolted together, and efficient improves greatly.
As preferably, the junction of above-mentioned first battery sheet and the described second battery sheet is positioned at the diagonal of described single crystal battery sheet body.As a rule, occur damaged near the intact single crystal battery sheet diagonal positions easily, therefore, when discarded single crystal battery sheet is cut, diagonal cutting along intact single crystal battery sheet, can farthest utilize discarded single crystal battery sheet, and the single crystal battery sheet that is stitched together is not easy to occur to damage again in this diagonal.
The utility model compared with prior art, have following beneficial effect: single crystal battery sheet body of the present utility model is spliced by two parts, and these two parts are respectively by cutting on the different waste battery sheets, can guarantee that not only spliced single crystal battery sheet normally uses, and effectively utilized discarded single crystal battery sheet, reduced the waste of resource.
