Description
Technical field
The utility model relates to solar cell.
Background technology
The single crystal silicon solar cell monomer can effectively absorb solar energy, and converts it into the semiconductor device of electric energy.The luminous energy of the sun is become the device of electric energy with materials such as Ban conductor Gui ﹑ selenium.Have excellent some ﹐ such as long ﹐ conversion efficiency height of high ﹐ life-span of reliability and can do the power supply of artificial satellite ﹑ boat mark lamp ﹑ transistor etc.Monocrystaline silicon solar cell is in silicon series solar cell, and the big sun of monocrystalline silicon can battery conversion efficiency the highest (16%～20%), and technology is also ripe.The electricity ground technology of monocrystalline silicon is own near ripe now, in battery is made, generally all adopts technology such as surface-texturing, emitter region passivation, subregion doping, and the battery of exploitation mainly contains plane monocrystalline silicon battery and grooving and grid burying electrode monocrystalline silicon battery.
Polysilicon solar cell has the material preparation process battery of new generation of advantage such as simplification relatively of high conversion efficiency and the long-life and the amorphous silicon membrane battery of monocrystalline silicon battery concurrently; Its conversion efficiency is generally about 12%; Be lower than single crystal silicon solar cell slightly, do not have obvious efficient decline problem, and might on the inexpensive substrate material, prepare; Its cost is far below monocrystalline silicon battery, and efficient is higher than the amorphous silicon membrane battery.
The production of monocrystaline silicon solar cell need consume a large amount of HIGH-PURITY SILICON materials, and it is complicated to make these material technologies, and power consumption is very big, and oneself surpasses 1/2nd in the manufacture of solar cells total cost.The pulled crystal silicon rod is cylindric in addition, and the microsection manufacture solar cell also is a disk, and it is low to form solar components plane utilance.Therefore, since the eighties, the development that more American-European countries have dropped into polysilicon solar cell.
There is unreasonable structure in existing polysilicon solar cell, the shortcoming that manufacturing cost is high.
Summary of the invention
The utility model provides a kind of high efficiency, low cost polycrystalline silicon solar cell, and the utility model has solved existing polysilicon solar cell and had unreasonable structure, the problem that manufacturing cost is high.
For addressing the above problem, the utility model adopts following technical scheme: the high efficiency, low cost polycrystalline silicon solar cell comprises polycrystalline silicon solar cell monomer 1, encapsulation square frame 2 and support 3; Polycrystalline silicon solar cell monomer 1 is square laminated structure; Encapsulation square frame 2 is square frame shapes, and some supports 3 are provided with in length and breadth and constitute the grid-shaped structure, and support 3 is arranged in the encapsulation square frame 2; Support 3 ends are fixed on the encapsulation square frame 2; Be provided with the groove 4 of square on the top of inside upper part that encapsulates square frame 2 and support 3 both sides, be provided with a polycrystalline silicon solar cell monomer 1 in each grid that support 3 constitutes, the edge of polycrystalline silicon solar cell monomer 1 is embedded in the groove 4.
The high efficiency, low cost polycrystalline silicon solar cell of the utility model has low, simple in structure, the convenient production of cost, advantage of high production efficiency.
