at present, more than 80% of solar cells produced globally use crystalline silicon, wherein the content of monocrystalline silicon is about 40%, the most significant advantage of monocrystalline silicon is that the conversion efficiency is high, but the production cost is high, and because the production level of the traditional monocrystalline silicon generation and processing enterprises is low and the generation technical level is not high, the production efficiency of single-product silicon is low and the cost is high, which is extremely not beneficial to the development of the single-product silicon generation and processing enterprises, the single-product silicon generation and processing enterprises are also searching for single-product silicon production methods for improving the generation efficiency and reducing the cost.
The production process of the monocrystalline silicon comprises the steps of charging and melting → necking growth → shouldering growth → equal diameter growth → tail growth.
(1) And (3) feeding, namely putting a polycrystalline silicon raw material and impurities into a quartz crucible, wherein the types of the impurities are determined according to the N or P type of the resistor, and the types of the impurities comprise boron, phosphorus, antimony and arsenic.
(2) And (3) melting, namely after the polycrystalline silicon raw material is added into the quartz crucible, closing the crystal growth furnace, vacuumizing, filling high-purity argon to maintain a certain pressure range, then opening a graphite heater power supply, and heating to the melting temperature (1420 ℃) to melt a plurality of silicon raw materials.
(3) Neck growth, after the temperature of the silicon melt has stabilized, the seed is slowly immersed in the silicon melt due to the thermal stress when the seed is in contact with the silicon melt field, causing dislocations in the seed which must be lost by neck growth. The necking growth is that the seed crystal is quickly lifted upwards, the diameter of the grown seed product is reduced to a certain size (4-6mm), and because the dislocation line and the growth axis form a crossing angle, the dislocation can grow out of the crystal surface as long as the necking is long enough, and the crystal with zero dislocation is generated.
(4) And (4) shoulder growth, namely after the neck is grown, reducing the temperature and the pulling speed to gradually increase the diameter of the crystal to the required size.
(5) After the neck and the fan part are grown, the diameter of the product rod can be maintained between plus and minus 2mm by continuously adjusting the pulling speed and the temperature, and the part with fixed diameter is called as the equal-diameter part. The single silicon wafer is taken from the equal-diameter part.
(6) Tail growth, after the equal diameter part is grown, if the product rod is separated from the liquid level immediately, the thermal stress causes dislocation and slip lines of the product rod. To avoid this problem, the diameter of the pin must be reduced slowly until it becomes sharp and separates from the liquid surface. This process is called tail growth. And the grown crystal bar is lifted to the upper furnace chamber to be cooled for a period of time and then taken out, thus completing one growth cycle.
The principle of forming the silicon single crystal rod is that when crystal pulling is carried out, required raw materials are put into a crucible to be heated, so that the raw materials are melted under the action of high temperature, then a single crystal pulling device is used for manufacturing the silicon single crystal rod, the phenomenon that the melted silicon single crystal raw materials are solidified due to the temperature reduction during the pulling is utilized, when the silicon single crystal rod is formed, a furnace cover needs to be covered on the upper portion of the crucible, the sealing between the furnace cover and the crucible is good, the speed of external impurities entering the crucible is prevented, the purity of the silicon single crystal rod is influenced, and under the condition, the speed of the silicon single crystal rod during the pulling is not too high, otherwise, the quality of the silicon single crystal rod is influenced.
Temperature control plays a crucial role in the quality and speed of single crystal silicon growth. The thermal field of the Czochralski single Crystal (CZ) method is a complex single crystal growth system consisting of a graphite piece system, a single-product furnace cooling system and an argon system. The cooling process of the czochralski method is carried out under the environment of introducing cooling gas (generally argon), the whole system is in an open state, the introduced argon stays in the furnace for a short time, the finally taken heat is 80% -85% of the total heat, the cooling effect is general, the cost of the cooling gas is high, the growth speed of the single crystal depends on the temperature gradient of a solid-liquid interface, the temperature gradient is larger, the growth speed is higher, but the temperature gradient is overlarge, and the problems of dislocation and the like in the crystal growth process can also be caused.
Through long-term research and practice, continuous exploration and improvement, the patent applicant of the utility model researches and invents the water cooling device which has excellent stability and better cooling effect and can improve the pulling speed of the single-product silicon.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
