The solar silicon single crystal rod adopting the design can avoid thickness unevenness during wire mesh cutting and can efficiently improve the quality of the wafer.
Description
Technical field
The utility model relates to the field of silicon rod, especially a kind of solar energy single crystal silicon rod.
Background technology
At present world's photovoltaic industry is with 31.2% annual average rate of increase high speed development, and it is the first to be positioned at global energy GENERATION MARKET rate of increase.Various countries launch respectively strong policy or formulate evolutionary operation(EVOP) according to this trend, make photovoltaic market present flourish general layout.In recent years, along with the fast development of photovoltaic industry, silicon single crystal was used to make solar cell, presented the situation that supply falls short of demand.Solar panel is under solar radiation, and luminous energy just changes into electric energy immediately, and can ceaselessly generate electricity, can non-stop run more than 20 years.The direct current that he sends can directly be supplied with electrical appliance, can also be stored in the store battery, and another mistake becomes the 220V/380V alternating-current, and then be assembled into the solar electrical energy generation unit, for various household electrical appliance, many silion cells can also be linked, be assembled into photovoltaic plant and transmit electricity to national grid.Solar-energy photo-voltaic cell is that country widelys popularize, and development prospect is bright, does not have the green energy resource that pollutes.
Silicon single crystal rod is the single crystal of silicon, is the crystal with basic perfect lattice structure, and diverse ways has different character, is a kind of good material of partly leading, and weak electroconductibility is arranged, and its electric conductivity increases with the rising of temperature, and significant semi-conductivity is arranged.When silicon single crystal rod line cuts, in the time of gauze contact crystal bar surface, because the effect of power causes the swing of silicon rod easily, so just cause easily the wafer became uneven that cuts out even, thereby cause the performance of wafer, in addition, at present existingly can only carry out single silicon rod cutting to silicon single crystal rod cutting, its cutting efficiency is low, cuts if stack up, thereby can cause again not lining up of silicon rod to cause cutting irregular phenomenon.
Summary of the invention
The technical problems to be solved in the utility model is: in order to overcome the problem of above-mentioned middle existence, provide a kind of solar energy single crystal silicon rod, its project organization rationally and be difficult in cutting process by abrasive material rush broken, yield rate is high.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of solar energy single crystal silicon rod; comprise that complex root silicon single crystal barred body is formed by stacking; the upper surface of described silicon single crystal barred body is provided with the protective membrane that fits with the silicon single crystal barred body; be coated with adhered layer on the protective membrane; the bottom of silicon single crystal barred body is provided with base plate; be coated with the Resins, epoxy adhered layer on the base plate, the both sides of silicon single crystal barred body are equipped with baffle plate, and the silicon single crystal barred body sticks on the base plate by baffle plate.
Further, the material of described adhered layer is that Resins, epoxy is made.
Reclaim for clout continuation that can cutting is enough, the adjacent seamed edge intersection of described silicon single crystal barred body cross section is chamfering structure, and the angle between its chamfering and the seamed edge is 60 °.
The length of described silicon single crystal barred body is 220～280mm.
The beneficial effects of the utility model are: described solar energy single crystal silicon rod, the silicon rod of this design can avoid occurring phenomenon in uneven thickness when carrying out the gauze cutting, can effectively improve the quality of wafer.
