It can be used for the production and deep processing of diode-level, rectifier-level, circuit-level and solar cell-level monocrystalline products, and its follow-up products integrated circuits and semiconductor separation devices have been widely used in various fields, and also occupy an important position in military electronic equipment.

With the rapid development of photovoltaic technology and micro-semiconductor inverter technology, solar cells produced by silicon monocrystalline can directly convert solar energy into light energy, realizing the beginning of the green energy revolution. The Beijing 2008 Olympic Games will show the "Green Olympics" as an important display to the world, and the use of monocrystalline silicon will be a very important part of it. Now, foreign solar photovoltaic power stations have reached the stage of theoretical maturity and are transitioning to the stage of practical application, and the utilization of solar silicon monocrystalline will be popularized all over the world, and the market demand is self-evident.

Hebei Ningjin Monocrystalline Silicon Industrial Park responds to this international trend and provides monocrystalline silicon products with excellent performance and complete specifications for the world.

Monocrystalline silicon products include 3"-6" monocrystalline silicon round rods, sheets and square rods and sheets, which are suitable for the production needs of various semiconductors and electronic products.

On July 1, 2008, Dacheng Silicon Technology Co., Ltd. and Jiangsu Huilun Co., Ltd. signed the "Purchase and Sales Contract" for the purchase and sale of solar monocrystalline silicon wafers in Zhenjiang City, Jiangsu Province.

Dacheng Silicon Technology Co., Ltd. provided 125mm 125mm solar monocrystalline silicon wafers to Jiangsu Huilun in accordance with the agreed technical label, with a contract amount of 453.33 million yuan, and the supply time was from the third quarter of 2008 to the end of the fourth quarter of 2009. 3. Zhonghuan Co., Ltd.: engaged in the research and development, production and sales of semiconductor discrete devices and monocrystalline silicon materials, the main products are high-voltage silicon stacks, silicon bridge rectifiers, fast recovery rectifier diodes, monocrystalline silicon and silicon cutting wafers, etc., among which discrete device products are mainly used in televisions, monitors, microwave ovens and other electrical appliances; Monocrystalline silicon materials are mainly used in semiconductor integrated circuits, semiconductor discrete devices, solar cells, etc.

The company and Aerospace Electromechanical jointly established Inner Mongolia Zhonghuan Photovoltaic Co., Ltd. to jointly build the Inner Mongolia photovoltaic industry base project. The project will be constructed in four phases, with the goal of building a production base with an annual output of 800-1000MW of solar monocrystalline silicon ingots and wafers. 4. Tuori New Energy:

In the world, only Siemens, Sharp, Germany RWE and other manufacturers can produce amorphous silicon, monocrystalline silicon, polycrystalline silicon three kinds of solar cells at the same time, the company is the only one, the company uses the production equipment self-made degree of up to more than 70. Break the double monopoly pattern of "foreign equipment monopoly and foreign technology and technology" in the domestic solar cell industry. 5. EGing Optoelectronics:

It will take the form of asset replacement and issuance of shares to purchase assets to place 100 shares of EGing Optoelectronics to enter the photovoltaic industry, and EGing Optoelectronics will also be successfully listed on the backdoor. It is understood that EGing Optoelectronics has formed a relatively complete photovoltaic industry chain, becoming one of the only solar cell module manufacturers in China with a vertically integrated industrial chain and a production capacity of more than 200MW. After the reorganization, Haitong Group's main business will be changed from the processing and sales of fruits and vegetables to the production and sales of monocrystalline silicon rods, monocrystalline silicon (polysilicon) wafers, solar cells and solar modules.

According to the latest data on January 11, 2020, the ** of monocrystalline silicon is about a few hundred yuan per unit, the cheap one is one or two hundred yuan, and the expensive one is several thousand yuan. Monocrystalline silicon with different functions and uses is also different.

Monocrystalline silicon has a diamond lattice, the crystal is hard and brittle, has a metallic luster, can conduct electricity, but the conductivity is not as good as that of metal, and increases with the increase of temperature, and has semiconductor properties.

Monocrystalline silicon can be used in the production and deep processing of diode-level, rectifier-level, circuit-level and solar cell-level monocrystalline products, and its follow-up products integrated circuits and semiconductor separation devices have been widely used in various collar and scatter base domains, and also occupy an important position in military electronic equipment.

The ** of monocrystalline silicon is about a few hundred yuan per unit, the cheap one is one or two hundred yuan, and the expensive one is several thousand yuan. Monocrystalline silicon for different functions and uses** is also different.

Monocrystalline silicon has diamond.

Lattice, the crystals are hard and brittle, have a metallic luster, and can conduct electricity, but conductivity.

It is inferior to metals and increases with increasing temperature, so it has semiconductor properties.

Monocrystalline silicon is an important semiconductor material.

Trace amounts of group IIIA elements are doped into monocrystalline silicon to form p-type semiconductors.

Incorporate trace amounts of group VA elements to form n-type, n-type and p-type semiconductors combined to make solar cells, which convert radiant energy into electrical energy.

One kilogram of monocrystalline silicon can be cut into 15-30 pieces, and the number of chips varies according to the radius of the silicon wafer.

Monocrystalline silicon refers to the single crystal of silicon. A crystal with a largely intact lattice structure. Different directions have different properties and are a good semiconducting material.

Purity is required to meet, or even be, above. It is used in the manufacture of semiconductor devices, solar cells, etc. It is made of high-purity polysilicon drawn in a monocrystalline furnace.

It depends on the diameter of the rod, because of different diameters, the length of 1 kilogram is different, the theoretical length of 1 kilogram is 6 inches, and the theoretical length of inches is, and the theoretical length of 8 inches is. And because the line groove of the line cutting is, 1 kg and 6 inches can theoretically be sliced, and the inch is a slice, and the 8 inch is a slice. In actual production, there are also fragments and other situations, so the actual number of pieces is not the same as the theoretical value.

The actual number of films is generally about 2-5 pieces less than that of theoretical films.

Look at what you are.

125 or 150.

There are also differences between polycrystalline and monocrystalline.

Generally, it is calculated by the length, about 3 slices per millimeter, which is not exactly the case.

Monocrystalline silicon wafer manufacturers include Jiangsu Haixiang New Energy Fangzhong Yuyuan Technology, Kirin Silicon Wafer Technology, ReneSola, Suntech Solar Power, Dacheng Silicon Technology, Changzhou Yijing Optoelectronics Technology, Beiyan Hebei Jinglong Group, Baoding Tianwei Yingli New Energy Peihua, Hejing Technology Co., Ltd., Ningbo Jingyuan Solar, etc.

Monocrystalline silicon wafer: A single crystal of silicon, which is a crystal with a basically complete lattice structure. Different directions have different properties and are a good semiconducting material.
