Q:After the completion of the silicon chip will appear in the shadow of the white spots or what is the situation? How to solve
There is a shadow or a spot to prove that there is an uneven phenomenon in the cleaning process
Q:How to convert photovoltaic silicon MW
Monolithic power conversion efficiency (x = 10000 x 1000, single area)More than and 156 crystal area: 243.34
Q:How to do on the silicon wafer
The general use of ultrasonic and pre cleaning (pickling) can be solved
Q:What is the use of silicon?
The domestic semiconductor leader GRINM (600206) general manager Zhou Qigang told reporters that the original price is less than $30 per kilogram of raw materials of polysilicon, now prices rose to about $110 per kilogram, affected by this, GRINM 2005 production costs increased by 30 million yuan.Zhou Qigang believes that the culprit is the price of polysilicon solar cells. Because of the global crude oil prices, rising demand for new energy in Europe and the United States, these countries have taken measures to encourage the development of solar energy, the solar energy industry is booming, leading to the surge in demand for polysilicon.
Q:Wafer size6 inches and 8 inches only refers to the diameter of monocrystalline silicon?
Refers to the diagonal length of the silicon waferBut you asked the wrong question, the wafer is divided into monocrystalline silicon and polycrystalline silicon wafer, you say is a square of silicon polysilicon film of silicon wafer, you ask in the four corner is a circular arc shape, so you should also count the length of the diagonal right. If not to shape the polysilicon film solution you can search the Internet search look.
Q:What are the reasons for the phenomenon of monocrystalline silicon chip
You say the phenomenon called flower piece, the formation of many factors, the main reason is that contamination, because in the process, the wafer surface after polishing the silicon atom is bond breaking, it is easy to adsorb metal ions and cannot completely by cleaning out.
Q:What is the specific way to clean the silicon wafer suede concrete steps
But when these two semiconductors are connected, they form a "P-N junction". When the current through the wire to the chip, the electron will be pushed to the P area, in the P area of the electron and hole compound, and then will be in the form of photon energy, which is the principle of LED luminescence. The wavelength of light is the color of light, which is determined by the material that forms the P-N junction. The utility model is a display screen which is used for displaying various information such as text, graphics, image, animation, quotation, video, video signal, etc. by controlling the display mode of the semiconductor light emitting diode.
Q:Why not use N type silicon crystal silicon battery
N type silicon wafer from the raw material price or quantity, and P type silicon wafer or some gap. This also led to the battery chip manufacturers for N battery has been in the laboratory stage, not mass production.Again, the P type battery is to take GA or boron, but the N type batteries into another material, I am not very clear, not engage in technology, huh, huh, huh, huh.The above information, I hope to help you.
Q:There is a micro structure on the side of the silicon wafer
For solar cells destined to enter the market market (mass) products, the advantages of reserves is also one of the main reasons for the silicon photovoltaic materials.
Q:What's the difference between a silicon wafer and a battery?
Silicon wafers are cut into pieces by wire cutting!The battery pack is a silicon wafer through the surface flocking, diffusion of PN junction, and then PECVD coating
