Q:How much a piece of silicon on the board
Crystalline silicon solar cell has a characteristic, that is a piece of 0.48-0.6V, accustomed to call 0. 5V, how many V you want, can be connected in series or in parallel to achieve. As for power, according to the W=UI formula can be drawn,
Q:What are the reasons for the phenomenon of monocrystalline silicon chip
Or storage time is too long, vacuum packaging problems, the outside world has the dust into the adsorption on the surface of silicon, this will happen. There is the central part of the polishing process, there is a problem of pressure, resulting in the removal of the center is not enough, the surface roughness is very poor, in the semiconductor level light irradiation, the center of the silicon will appear black.
Q:Manufacturers of solar wafers belong to the photovoltaic industry which specific industry classification below
There is no specific classificationPhotovoltaic industry can be divided into the upper and middle reaches of the upper reaches of the main silicon material, silicon products, the middle reaches of the main battery, components, the lower reaches of photovoltaic power generation
Q:What is a silicon chip made of?
A simple understanding of the silicon wafer is a silicon material cut into pieces by processing. Silicon is a kind of high hardness material, silicon material looks like a stone, he must be washed clean and then heated by a stove melt forming a bulk silicon ingot, and then use the special machine to slice into pieces.
Q:Solar silicon wafer cutting fluid can burn explosion?
2, the glass can not be used as the bearing plate of the crystal rod, if the use of graphite plate, grinding down the silicon powder containing a certain amount of graphite, it is difficult to deal with the recovery of silica fume3, can only be used for single crystal cutting4, the cost of the problem, and now the price of diamond wire fell faster, diamond wire cutting costs should be close to the cost of cutting free abrasive
Q:Why do monocrystalline silicon chamfer? Polysilicon film?
There are many single crystal chamfer.Single crystals are generally large chamfer, there is a single crystal process decision. There is a single crystal silicon rod is cut out, in order to make full use of the silicon rod, appear large chamfer; and polycrystalline is generally small chamfer, is to reduce the crack edge of the silicon wafer, the external stress of the silicon wafer or cell rupture. Polycrystalline battery will also appear large chamfer, those are generally small chamfer of the battery, found that there is a problem after the cut into large chamfer.
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 the purpose of wafer cleaning and the cleaning of silicon material, what is the difference between the acid used
A technique used to reduce the reflectivity of silicon, which is cleaned only by hydrofluoric acid
Q:How to detect the surface finish of photovoltaic silicon wafers, what equipment?
Do you want to check the surface roughness or do you want to clean it? These two are not the same,
Q:What is the role of silicon wafer annealing furnace, what specific requirements
The silicon wafer contact material uses the quartz material, does not contact the metal material
