How much harm silicon on the human body
- Silicon is a semiconductor material, if it is to detect the bare silicon wafer, then there is no harms
Solar power generation system suitable for home, how much is the cost of a set?
- Then the 1000 Watt Solar panel price is 5000 yuan -10000 yuan, regardless of inverter and power generation, but with the power of the household appliances related to property, if you use ordinary household appliances 100 watt power inverter, then with a 300-500 tile, if you are using a blender or high power desktop computer although only 100 watts -200 watt but starting current, so the best 1000 Watt inverter. The price of the inverter is 800-2000 yuan (depending on the power and performance price).s
How much do solar energy panels cost?
- Buying solar panels can be very expensive, especially for installation. If your average daily usage is 6.6 kilowatt per hour, then you would need a 2 kilowatt system that could generate ten kilowatts per hour in a day. This system could cost between $0,000 to $20,000. Of course, the higher wattage, the higher the cost. There are some alternatives to spending thousands of dollars on solar panels. ) Buy several solar panel kits and link them together yourself. 2) Combine solar with wind power to decrease the number of panels you will need. 3) Build your own solar panels for around $200 each. If you are handy with some basic soldering, then you can make your own solar panels.s
Silicon rod / wafer processing production
- Another reason is that CZ is easier to produce large size single crystal silicon rods than FZ method. At present, using the method of CZ CZ main equipment: CZ growth furnace growth furnace by CZ components can be divided into four parts: (1) the furnace body comprises a quartz crucible, graphite crucible, heating and insulating element in the furnace wall (2) crystal and crucible for rotary mechanism: including seed chuck, hanging and pulled the rotating element (3) atmosphere pressure control: including gas flow control, vacuum system and pressure control valve (4) control system: including the detection sensor and computer control system processing: charging, melting, necking, shoulder growth, growth, growth and diameter growth of the tail (1) charging: the polysilicon raw materials and impurities in the quartz crucible, the type of impurity depends on the N or P type resistance. Boron, phosphorus, antimony, arsenic. (2): after the melting quartz crucible for polysilicon feedstock after long crystal furnace must be closed and vacuum filling in high purity argon to maintain a certain pressure range, and then open the graphite heater power supply, heating to the melting temperature (1420 DEG C) above, the polysilicon raw material melting. (3) necking growth: when the temperature of the silicon melt is stable, the seed is slowly immersed in the silicon melt. Because of the thermal stress in the contact between the seed and the silicon melt, the seeds will be dislocation, which must be used to reduce the growth of the crystal. Necking is the seed growth will rapidly upward, the seed crystal grows to a certain size of the reduced diameter (4-6mm) due to the dislocation line and growth axis into a corner, as long as the neck is long enough, the dislocation can grow the crystal surface, zero crystal dislocation.s

What do i need to use a 2v solar panel to charge a 6v lead acid battery as i cant find a 2v to 6v regulator?
- Buy the proper charger or get a degree. Don't screw with making a charger for a lead acid battery of you don't know what you are doing. You could get hurt. You need a hell of a lot more than just a regulator.s
What is the cutting fluid for solar wafer cutting?
- Because in the China multi wire cutting machine was first used in semiconductor cutting, so that only the Swiss MB and HCT, the Swiss system thinking line cutting machine with special emphasis on power and environmental protection, so that this kind of machine in the cutting process of mortar viscosity requirement is relatively high, the most direct embodiment is to use the cutting fluid is oily, reflected in the raw material cutting fluid is used to peg, otherwise, the power will be the formation of excess waste machine. NTC is the rise in the solar industry on the occasion, we seize the opportunity, to imitate the Swiss line cutting machine design and production, but the Swiss precision machine modified to virtually out of order, the rapid development of the pursuit of efficiency of solar wafer cutting industry, especially to the rise of China solar wafer cutting industry thus, China quickly occupied the market leader, the share reached 65%. However, the company has done a little better, although the power system and the power of the machine to reduce a lot, you can use the machine in the use of cutting fluid on the Swiss machine standards. Oily cutting fluid cutting efficiency and surface cut out of the film is generally better than the aqueous solution of cutting fluid, but the performance of Japanese light wire cutting machine, which he used oily fluid will cause a burden on his power, so Japanese developed this kind of water-based cutting fluid. Regardless of the cost or the use of the Japanese machine are more consistent, and easy to recycle. This NTC machine oil cutting fluid and water-based cutting fluid can be used.s
in a solar panel, where do the protons go?
- Here okorder.com/... Within this structure, the electrons are not really lost from the system. An electron just gets enough energy (from light) to be able to leave its atom, and float freely around the structure. Hence you have electrons in motion, which is the definition of electric current. If the lights go out, the electrons just settle back into one of the atoms that is missing an electron.s
