Q:The purpose and means of chemical etching of silicon wafers?
Corrosion is to create suede, was not intended to be clean, but cleaning agents will inevitably etch the surface damage layer of wafer line after cutting in the solar industry is a must, because it can produce suede.
Q:How to deal with silicon wafer annealing
Why anneal? One reason is that silicon contains oxygen, oxygen has the role of absorbing impurities. The oxygen near the surface of the silicon wafer can be removed from the surface during annealing, so as to reduce the number of impurities near the surface. Facilitates device fabrication;Annealing has a certain influence on the resistivity and minority lifetime.For reference.
Q:What is the surface hardness of monocrystalline silicon and polycrystalline silicon wafers
At this time, the hardness and elastic modulus of the oxide layer on the surface of monocrystalline silicon wafer were measured, which were about 10.2 GPa and 140.3 GPa, respectively. When the contact depth is about 32 ~ 60NM, silicon wafer contact stiffness and contact depth into a non linear relation between the hardness and elastic modulus increased sharply with the contact depth, show that the hardness and elastic modulus of monocrystalline silicon oxide film surface layer is affected by the matrix material.
Q:Why silicon wafers are made in watts!
Crystalline silicon photovoltaic cells have two types of monocrystalline silicon and polycrystalline silicon, with P (or n) silicon substrate, through the formation of phosphorus (or boron) diffusion Pn formation, production technology is mature, is the leading product in the photovoltaic market. The buried layer electrode, surface passivation, enhanced light trapping, dense grid technology, optimization of back electrode and contact electrode technology, improve the collection efficiency of carrier materials, optimization of anti elbow membrane, concave convex surface, high reflective back electrode, the photoelectric conversion efficiency is greatly improved. Silicon photocell area is limited, the larger the phi 10 to 20cm wafer, the annual production capacity of 46MW/a. At present, the main task is to continue to expand the scale of the industry, the development of ribbon silicon photovoltaic technology, improve material utilization. Internationally recognized as the highest efficiency under AM1.5 conditions of 24%, the space with high quality efficiency in the AMO condition is about 13.5 - 18% of the ground with a large number of production in the AM1 conditions in the more than 11 - 18%. It can reduce the cost, but the efficiency is lower, which is made by the method of directional solidification. Optimization of the silver electrode and aluminum paste screen printing, grinding and polishing process, do everything possible to further reduce costs, improve efficiency, the maximum conversion efficiency of polycrystalline silicon photovoltaic cells up to 18.6%.
Q:Ultrasonic cleaning cleaning silicon?
1, silicon wafer wafer ultrasonic cleaning function.2, cleaning the wafer production process, pollutants using ultrasonic cleaning machine effectively remove organic matter, wafer surface particles and metal impurities, natural oxide layer and quartz, plastic containers and accessories, the wafer surface damage characteristics. According to different cleaning process, the corresponding cleaning unit is equipped with independent control.
Q:How much harm silicon on the human body
If it is at least module, such as CVD PVD, there are some toxic gases
Q:What is the silicon area of the 125 diagonal of a single crystal of 160?
160 refers to the diagonal length of the chamfer, you draw a map can be calculated, the specific algorithm is:

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:What is the difference between silicon wafer P111 and P100
If the crystal is body centered cubic lattice, the crystal orientation through the cube on the diagonal atoms
