The raw material of the solar cell is the silicon chip, some manufacturers specialize in the production of monocrystalline silicon, polycrystalline silicon chip, the production of monocrystalline silicon, polycrystalline silicon chip, what is the use of raw materials? Also ask how much raw material costs in recent years? Thank you！！
Polysilicon material:1 solar polysilicon: 6N, P2 head tails: P3 broken semiconductor wafer: P type, arc type debrisPrice: $200 / kg
As a variable current switch, the transistor can control the output current based on the input voltage. Different from the common mechanical switch (such as Relay, switch), the transistor uses the electrical signal to control the opening and closing, and the switching speed can be very fast, the switching speed of the laboratory can reach more than 100GHz.
Transistor (transistor) is a kind of solid state semiconductor device, which has many functions such as detection, rectification, amplification, switching, voltage regulation, signal modulation and so on.
Silicon transistorSemiconductor materials can be divided into silicon and germanium transistors. According to the polarity of the transistor can be divided into germanium NPN transistor, germanium PNP transistor, silicon NPN transistor and silicon PNP transistor.
