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:Pure curiosity why silicon wafer is round
Major manufacturers are trying to expand the cross-sectional area of monocrystalline silicon, not just to cut more wafers per wafer...It's a waste of a lot of material if it's easy.
Q:Why silicon wafers are made in watts!
Battery specifications good variety:103*103mm125*125mm150*150mm156*156mmThe longest seen is the single crystal 125*125mm polycrystalline 156*156mm according to the efficiency to determine the current efficiency of the battery chip is 16%--19%
Q:8 inch monocrystalline silicon area?
8 inch silicon wafer, refers to the diameter of 8 inches,1 inches =25.4mm=2.54cm
Q:The significance of silicon wafer heat treatment
The significance of silicon wafer heat treatmentHeat treatment temperature requirements: 650 + 5 c;The purpose of heat treatment is to restore the true resistivity of Czochralski silicon wafers;
Q:For solar wafer cutting diamond wire, what are the characteristics?
The diamond wire saw is referred to as diamond wire, diamond wire, are the different names of one thing, because it is the thread sawing, all wire - sometimes called is a steel wire electroplating a layer of diamond particles consolidation.
Q:How to avoid or reduce the fragmentation of thin silicon wafers without wax polishing?
I don't know how your employees operateYou can put a small bubble in the insertion box below if it is convenient. Can play a buffer role
Q:How to do on the silicon wafer
3, water cleaningThis step is very important! Do not wash the water in order to save trouble after the end of washing. Rinse the small dust, particles, and other debris washed off during the scrubbing process.
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:Begged monocrystalline silicon rod is to use what tools and equipment to cut into silicon
General loss of about 40%, the general thickness of about 190um silicon, cutting seam in 120um
