Q:The production of silicon units do front-line production workers harmful to the body
The two stage is the most important process of production silicon ingot and slicing stage in the production process, GT ingot furnace and HCT slicing machine are relatively closed production, metallurgy, nonferrous metal, chemical industry, harm can be ignored
Q:How to make monocrystalline silicon solar cells
Surface fleeceThe preparation of single crystal silicon wafer is the use of anisotropic etching of silicon on the surface of the silicon per square centimeter to form several million square pyramidal structure, namely, the Pyramid structure. Due to the multiple reflection and refraction of incident light on the surface, the absorption of light is increased, and the short circuit current and conversion efficiency are improved. Anisotropic etching of silicon in alkaline solution liquid is usually hot, available alkali sodium hydroxide, potassium hydroxide, lithium hydroxide and ethylenediamine etc.. Most of them were prepared by using dilute sodium hydroxide solution with a concentration of about 1%, and the corrosion temperature was 70-85. In order to obtain a uniform texture, but also in the solution add alcohols such as ethanol and isopropanol as complexing agent to accelerate the corrosion of silicon. In the preparation of velvet, the silicon chip must be first surface corrosion, alkaline or acidic etching solution to about 20 ~ 25 m, corrosion in the face, the general chemical cleaning. After surface preparation of silicon wafers are not suitable for long-term storage in the water, in order to prevent contamination, should be spread as soon as possible.
Q:Why should the wafer cut side, cut out edge Jiaosha
To determine the crystal, cutting the adhesive carbon or glass, mounted on the fixed equipment.In simple terms is to determine the crystal direction, in order to facilitate future cutting, design graphics to consider this point, and then ask a little deeper, it is necessary to look at the book.Transistors in general with 111 sides, MOS general 110The reason for this is related to doping, corrosion and other post production, but also the activity of different layers of electrons is different, potential energy is not the same.
Q:What is the specific way to clean the silicon wafer suede concrete steps
LED (Light Emitting Diode), light emitting diode, referred to as LED, is a kind of power can be converted into visible light solid-state semiconductor devices, which can directly convert electricity into light. The heart of LED is a semiconductor chip, one end of which is attached to a support, one end is a negative electrode, and the other end is connected with the positive electrode of the power supply so that the whole chip is encapsulated by epoxy resin. The semiconductor chip is made up of two parts, one part is the P type semiconductor, in which the hole is dominant, the other end is the N type semiconductor.
Q:What is the price of monocrystalline silicon
The content of silicon in the earth's crust is 25.8%, which provides an inexhaustible source for the production of monocrystalline silicon. Because silicon is one of the most abundant elements in the earth, the solar battery that destined to enter the mass market (mass market) products, reserves of advantage is to become one of the reasons the main photovoltaic silicon materials.
Q:Monocrystalline silicon processing technology
The use of more than one set of cutting lines is an innovative way to increase the output of the machine under the condition of keeping the speed. The latest MaxEdge system of applied materials company uses a unique set of two independent control cutting components.MaxEdge is the industry's first use of specially designed fine wire secant system, the minimum can reach 80 M. Compared with the HCT B5 wire system applied materials industry leading, these improvements reduce the loss of the silicon material yield up to 50%.Wire system with higher productivity can reduce the number of tools in wafer yield under the same. Therefore, manufacturers can significantly reduce the cost of equipment, operators and maintenance.Reducing the consumption of silicon wafers is directly reducing the cost per watt of solar power.Wire products marketThe silicon wafer suppliers and hope to integrate the crystalline silicon PV module manufacturers to control their own slice process requires the use of wire saw device. Monocrystalline silicon and polycrystalline silicon photovoltaic technology are needed to use it.
Q:P type and N type monocrystalline silicon chip difference?
The N type is an electronic conduction, and the P type is a hole conduction
Q:What is the use of silicon?
The domestic semiconductor leader GRINM (600206) general manager Zhou Qigang told reporters that the original price is less than $30 per kilogram of raw materials of polysilicon, now prices rose to about $110 per kilogram, affected by this, GRINM 2005 production costs increased by 30 million yuan.Zhou Qigang believes that the culprit is the price of polysilicon solar cells. Because of the global crude oil prices, rising demand for new energy in Europe and the United States, these countries have taken measures to encourage the development of solar energy, the solar energy industry is booming, leading to the surge in demand for polysilicon.
Q:What is the difference between the purpose of wafer cleaning and the cleaning of silicon material, what is the difference between the acid used
The silicon wafer cleaning is also known as the production of wool, chemical etching of silicon wafer surface, so that the light area
Q:Why do you choose a silicon chip as a chip?
Silicon is a semiconductor, of course, germanium is also, but silicon is easy to find, you go to the ground to see is the siliconPhysical principles on the complex, the first point of memory knowledge to say it, we generally say how much G, strictly speaking, GB, 1GB=1024MB
