Q:Is the thickness of solar cell silicon wafer certain? Specifically how much
The rest is just the substrate, it doesn't work. Do not understand, then you can look at the film thickness of the battery, you will understand.
Q:Why the resistivity of silicon wafer is high and low
For example, after heating resistance and cooling, more or less there will be changes in the normal temperature change, is allowed error.
Q:What is the surface hardness of monocrystalline silicon and polycrystalline silicon wafers
When the contact depth is about 20 ~ 32nm, the contact stiffness and the contact depth of the single crystal silicon wafer are linear,
Q:How to calculate the conversion efficiency of monocrystalline silicon
Proportion of dark current - Irev>6 cell ratioThe proportion of low efficiency tablets - the proportion of P156Eff<14.5% batteries8 inch single crystal conversion rate of about 18.5%; a single conversion rate of about 9 inches in about 18.6%; quasi single crystal (large particles) probably about 18%; the new diamond wire cutting rate can be converted to about 18.92%.
Q:What is the cutting fluid for solar wafer cutting?
MB, HCT, NTC and other machines, the requirements of silicon cutting fluid and the proportion of silicon carbide powder is generally controlled at 1:0.92-0.95, mortar density in 1.630-1.635 can be cut quite ideal. Even if there is a greater proportion of proportion, and even mortar density of 1.67 or so will not have any problems, as long as the mortar viscosity control in 200--250 can be. But Ernst machine for mortar density is not higher than 1.57, that is to say 1.55-1.57. can control the viscosity of mortar at around 150, so the domestic silicon cutting fluid will appear in the 1.57 density with mortar, mortar viscosity may be less than 120, and if the mortar viscosity density to 150, more than 1.57, even more than 1.60. The viscosity of mortar is too large, directly will cause the machine alarm, actually influence deeper and may cause the film does not wash clean, burn, or heating of the motor, bearing on the machine itself is very wear.Therefore, the current domestic solar silicon cutting fluid, it is not very suitable for the Ernst & Young machine. The good news is that domestic users have found the defects of the machine, the machine began to replace the mortar pump from the original 0.75KW into 1.5KW, which may solve this problem.
Q:Light doped and heavily doped silicon wafers
Is divided into light heavy doping, which is related to the amount of doping
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
2, heat treatment of several temperature interval concept:Thermal donor: 350-550 degrees Celsius, 450 degrees Celsius450 C after heat treatment (or equivalent effect, such as the cooling of a single crystal in a furnace), the resistivity of the N type sample can be decreased and the resistivity of the P type sample is increased, as is the introduction of a certain number of donor phenomena. This is due to the temperature of the dissolved oxygen atoms in the formation of complex (SiO4) caused by the thermal donor, the resistivity of silicon and oxygen content of the four side is inversely proportional to.New donor: 550-800 DEG C, on behalf of the temperature of 650 degrees Celsius
Q:How many watts can a piece of silicon produce
A piece of silicon, has been able to integrate 160 thousand transistors. What a fine project! This is the crystallization of multidisciplinary collaborative efforts, is another milestone in the progress of science and technology.
Q:Why do you choose a silicon chip as a chip?
What we're talking about is charging or discharging a capacitor,The capacitance of the electricity is not easy to put the end, in theory, is to be able to 100 years, in fact, and there are different, which is why some of the memory card for a long time on the bad reasonProcessing technology is not easy to say, anyway, there is no level in China, the study did not useProbably and CPU processing technology is the same
