Abstract
The utility model discloses a polycrystal solar cell, which belongs to the technical field of semi-conductors. The polycrystal solar cell comprises a quadrilateral polycrystal cell main body, and the four edges of the quadrangle are connected through curved segments. Compared with the prior art, the polycrystal solar cell is processed by a waste polycrystal cell, and has the advantages of saving the cost and reducing the resource waste; on the other hand, the four edges of the polycrystal solar cell are connected through the curved segments, so that the structure is more stable, and damage can not be caused easily.
Description
Technical field
The utility model relates to a kind of solar energy polycrystal battery sheet, belongs to technical field of semiconductors.
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.
The shape of polycrystalline battery sheet of the prior art is square normally, because it is irregular to be used to make the crystal orientation of polysilicon chip of polycrystalline battery sheet, it is damaged easily in production and use, thereby cause the breakage of polycrystalline battery sheet, and all be to do waste treatment usually for the polycrystalline battery sheet that has damaged now, cause the great wasting of resources, and in fact, the polycrystalline battery sheet that these have damaged is available cutting the rear section again.
Summary of the invention
The utility model is at deficiency of the prior art, provide a kind of simple in structure, do not allow flimsy solar energy polycrystal battery sheet.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of solar energy polycrystal battery sheet, comprise polycrystalline battery sheet body, described polycrystalline battery sheet body is a quadrangle, and described tetragonal four edges is connected by arc.The utility model at first utilizes discarded polycrystalline battery sheet to process, and has the saving cost, reduces the advantage of the wasting of resources; On the other hand, four edges of the present utility model is connected by arc, and its structure is more stable, is not easy to damage.
As preferably, above-mentioned quadrangle is a square.Polycrystalline battery sheet body is done quadrate all equates the length of side on each limit, more convenient when the assembly unit battery pack.
As preferably, the distance between two relative straight lines of above-mentioned polycrystalline battery sheet body is 125 millimeters.This preferred version mainly is in order to be complementary with polycrystalline battery sheet of the prior art, to make its scope of application wideer.
As one of preferred version, above-mentioned arc all is positioned on the same circle, and this diameter of a circle is 165 millimeters.
As another preferred version, above-mentioned arc all is positioned on the same circle, and this diameter of a circle is 150 millimeters.
The utility model compared with prior art has following beneficial effect: the utility model at first utilizes discarded polycrystalline battery sheet to process, and has the saving cost, reduces the advantage of the wasting of resources; On the other hand, four edges of the present utility model is connected by arc, and its structure is more stable, is not easy to damage.
