Abstract
The utility model discloses a single-crystal solar cell, which belongs to the technical field of semi-conductors. The single-crystal solar cell comprises a quadrilateral cell main body with four right vertical angles. Compared with the prior art, the single-crystal solar cell is processed by a waste single-crystal cell, and has the advantages of saving the cost and reducing the resource waste; on the other hand, the four corners of the single-crystal solar cell are right angles, the generated power of the cell is in proportion to the area of the cell, and owing to the four right-angled corners, the surface area of the cell is larger; besides, when the single-crystal solar cells are assembled into a battery pack, clearance hardly exists among the cells. Therefore, compared with a conventional single-crystal cell, the single-crystal solar cell also has the advantage of high generated power, and achieves more sufficient utilization of installation space when utilized to assemble the battery pack.
Description
Technical field
The utility model relates to a kind of solar energy single crystal battery 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 solar energy 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, and 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, and in fact, the single crystal 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, and a kind of simple in structure, solar energy single crystal battery sheet that photoelectric conversion efficiency is high 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 solar energy single crystal battery sheet, comprise battery sheet body, and described battery sheet body is four quadrangles that drift angle all is right angles.The utility model at first utilizes discarded single crystal battery sheet to process, and has the saving cost, reduces the advantage of the wasting of resources; On the other hand, four angles of the present utility model are the right angle, because the generated output of battery sheet is directly proportional with its area, the shape that four angles are the right angle makes that the surface area of battery sheet is bigger, and when utilizing the utility model to be assembled into battery pack, the gap between battery sheet and the battery sheet does not almost have, therefore, the existing relatively single crystal battery sheet of the utility model also has the generated output height, utilize its when the assembly unit battery pack to the more sufficient advantage of the utilization of installing space.
In order to obtain better technique effect, further corrective measure also comprises: above-mentioned battery sheet body is square.Battery sheet body is done quadrate all equates the length of side on each limit, more convenient when the assembly unit battery pack.
Preferably, the length of side of above-mentioned battery sheet body is 125 millimeters.This preferred version mainly is in order to be complementary with battery sheet of the prior art, to make its scope of application wideer.
The utility model compared with prior art has following beneficial effect: the utility model at first utilizes discarded single crystal battery sheet to process, and has the saving cost, reduces the advantage of the wasting of resources; On the other hand, the existing relatively single crystal battery sheet of the utility model also has the generated output height, utilize its when the assembly unit battery pack to the more sufficient advantage of the utilization of installing space.
