Product Description:


Solar panel refers to a panel designed to absorb the sun's rays as a source of energy for generating electricity or heating. A PV module is a packaged, connected assembly of typically 6×10 solar cells. Solar PV panels constitute the solar array of a photovoltaic system that generates and supplies solar electricity in commercial and residential applications.

 Main Characteristic

Q:What is the harm of silicon chip into the fingers?
It is best to take out as soon as possible, otherwise easy to infection,
Q:What does TTV mean in silicon wafer production?
TTV, of course, the smaller the better. TTV is a measure of the quality of the silicon wafer is a very important indicator of process control, steel wire inspection, roundness is exceeded, the life of the guide wheel is up, the fixture is a problem, etc..
Q:Hydrogen passivation mechanism of hydrogen fluoride HF in silicon wafer RCA cleaning process
Wire cut damage layer thickness of 10 microns.Generally use 20% alkali solution in the corrosion condition at 90 C
Q:1 megawatts of solar energy need how many wafers
Now on the market every piece of the specification is not enough, there are 40W 60W 100W, etc.. One megawatt is equal to 100 watts, yourself.
Q:Wafer cutting will appear thick sheet, I would like to ask what the reasons are
Silicon wafer wire cutting will appear thick sheet, for the following reasons:1, the whole chip thickness:The A. guide slot is not uniform. Wafer thickness = slot steel wire diameter -4 times (SIC) D50, according to the requirements of wafer thickness required, you can calculate the best slot. In addition, because in the cutting process, steel wire wear, steel wire diameter decreases, and the port changed from round to oval, so the guide slot should be compensated according to the loss situation, to ensure the uniformity of wafer thickness.
Q:Light doped and heavily doped silicon wafers
Otherwise, the light is mixed, N++/P++ said heavy doping, no plus is light, thank you
Q:I would like to ask the solar cell (silicon) production process is the principle of how
Two, the surface of cashmereThe preparation of single crystal silicon wafer is the use of anisotropic etching of silicon on the surface of the silicon per square centimeter to form several million square pyramidal structure, namely, the Pyramid structure. Due to the multiple reflection and refraction of incident light on the surface, the absorption of light is increased, and the short circuit current and conversion efficiency are improved. Anisotropic etching of silicon in alkaline solution liquid is usually hot, available alkali sodium hydroxide, potassium hydroxide, lithium hydroxide and ethylenediamine etc.. Most of them were prepared by using dilute sodium hydroxide solution with a concentration of about 1%, and the corrosion temperature was 70-85. In order to obtain a uniform texture, but also in the solution add alcohols such as ethanol and isopropanol as complexing agent to accelerate the corrosion of silicon. In the preparation of velvet, the silicon chip must be first surface corrosion, alkaline or acidic etching solution to about 20 ~ 25 m, corrosion in the face, the general chemical cleaning. After surface preparation of silicon wafers are not suitable for long-term storage in the water, in order to prevent contamination, should be spread as soon as possible.
Q:What is the silicon area of the 125 diagonal of a single crystal of 160?
Because monocrystalline silicon and the battery is not a quadrilateral, so the 125 refers to the length of a single crystal square
Q:Silicon wafer cleaning after the two sides of the upper and lower grille also has a basket of flowers (Bai Yin)
I used to solve this problem for several months before the DOE experiment to solve, so it is very difficult, and there is no relationship with the bubble, and now the cleaning process does not need to bubble
Q:How to do on the silicon wafer
The general use of ultrasonic and pre cleaning (pickling) can be solved
