Q:One hundred watts of solar panels to how many pieces of silicon wafers, 156 of single crystals and polycrystalline
As for the power, according to the W=UI formula can be obtained, since a single voltage is fixed, the resulting current size determines the power of a battery, the current per tablet produced is not fixed, with the conversion rate of the conversion rate, high current is large, the reverse is small; the same the power conversion rate is high, the area is small
Q:The metal in the silicon wafer
Monocrystalline silicon or polycrystalline silicon chip to askSilicon is an important semiconductor material, chemical element symbol Si, the silicon used in the electronic industry should have high purity and excellent electrical and mechanical properties. Silicon is one of the largest and most widely used semiconductor materials, and its output and consumption mark the level of a country's electronics industry. In the research and production, silicon materials and silicon devices promote each other. In the Second World War, the use of silicon to produce high-frequency radar crystal detector. The purity of silicon is very low and not single crystal. In 1950, the first silicon transistor was developed to improve the interest of preparing high quality single crystal silicon. Czochralski silicon (CZ) was successfully used in 1952. In 1953, the crucible free zone melting (FZ) method was developed, which can be used for physical purification and single crystal pulling. In 1955, four pure silicon was produced by zinc reduction method, but it could not meet the requirement of manufacturing transistor. In 1956 of hydrogen reduction method of trichlorosilane. The amount of impurities in silicon and after a period of exploration after hydrogen reduction of trichlorosilane method has become a kind of main method.
Q:What are the raw materials of silicon wafers
As a variable current switch, the transistor can control the output current based on the input voltage. Different from the common mechanical switch (such as Relay, switch), the transistor uses the electrical signal to control the opening and closing, and the switching speed can be very fast, the switching speed of the laboratory can reach more than 100GHz.
Q:Why integrated circuit electronic devices should be integrated on silicon
Another image, that is, the integrated circuit is a combination of some electronic components and wiring, no insulation and insulation as a support. It is achieved by adding bias and other techniques to isolate.And for why it's cheaper to use silicon, it's not because of its semiconductor nature that it uses it. The formation of P and N, a multi hole, a multi electron, and thus the role of different doping. GaAs expensive, but the performance is good, mostly for high-speed circuits and military aspects.
Q:The last time you gave me the answer to the silicon chip, I learned a lot
Mohs hardness: 9.Density: 4 (+0.10, 0.05) g/cm 3.Optical characteristics: inhomogeneous body, one axis crystal, negative light.Color: strong. Blue: blue, green and blue; green: green, yellow and green; yellow: yellow, orange, orange orange; orange; pink: pink, purple, purple, purple and pink.Refractive index: 1.762 ~ 1.770 (+0.009, 0.005).Birefringence: 0.008 ~ 0.010.Ultraviolet fluorescence: Blue: long: no Xeon, orange; HF: no to weak, orange.Pink: long: strong, weak, orange orange; short wave.Orange: No, long wave strong, orange.Yellow: long: no to, red orange, orange red to orange: weak short wave.Color: purple, long wave: no Xeon, red; HF: no to weak, red.Colorless: no to medium, red to orange.
Q:How many times is the resistance of the same size silicon
How many times is the resistance of the same size silicon
Q:What to do with silicon. What is the relationship between the semiconductor and the PCB board
But a good silicon chip is not available. Because the bare silicon wafer is not easy to damage and difficult to connect. This is a process of binding, the so-called binding is bound to use a very fine gold wire from the silicon chip lead wire, received on the metal pipe, and then use the non-conductive plastic to bind the chip sealed. We generally see transistors, chips, etc. are packaged, you simply can not see the inside of the core. Of course is also useful in metal or ceramic chip shell, such as the two or three level of some high power tubes, military grade components etc., but because the metal and ceramic package cost is relatively high, so most of the circuit or engineering plastic package.PCB is a printed circuit board, is what we call the board. The copper wire and the welding of various components and chips. The manufacturing of printed circuit board, you should check the information bar, then I talk today what also don't want to do
Q:After wafer cleaning, how to change the film?
2, surface metal cleaning(1) HPM (SC22) cleaning (2) DHF cleaningMetal contamination of silicon surface has two kinds of adsorption and desorption mechanism: (1) compared with the negatively charged silicon high metal such as Cu, Ag, Au, from the silicon surface to capture electron on the surface of the silicon direct formation of chemical bonds. Has a high redox potential of the solution to obtain electrons from these metals, resulting in metal the ionized form dissolved in the solution, so that this type of metal removed from the silicon surface. (2) compared with the negatively charged silicon low metal, such as Fe, Ni, Cr, Al, Ca, Na, K can be easily ionized in solution and deposited on the silicon wafer surface natural oxide film or a chemical oxide film on these metals in dilute HF solution with a natural oxide film or a chemical oxide film is easily removed.3, organic cleaningThe removal of organic silicon surface cleaning fluid used is SPM.SPM with high oxidative capacity, metal oxide can be dissolved in solution, and the oxidation of organic compounds to produce CO2 and.SPM cleaning water can remove the surface of silicon wafer heavy organic contamination and some metal, but when organic contamination is heavy will make carbonization of organic matter and difficult to remove by SPM. After cleaning, the silicon surface residual sulfide, the sulfide particles is difficult to use to water wash out.
Q:Is the thickness of solar cell silicon wafer certain? Specifically how much
140-230 bar, see the specific requirements, most of the requirements of 200
Q:The relationship between the weight and the power of solar wafers!
156*156,8 inch polysilicon chip Accounting: efficiency of 16%, the thickness of the silicon chip is 180, corresponding to the amount of polysilicon per watt on the map is 7G.
