In the traditional acid method, the texturing process is mainly oxidation reaction. Points on the silicon surface randomly become oxidation or reduction sites and they act like localized electrochemical cells . The chemical reaction is given below: In this reaction, cracks and fractures are uncovered by etching and new etch. .
In Ag/Cu MACE method, metal particles are deposited on substrates at first. Deposition of Ag and Cu shares the same reaction mechanism. Take. .
After mc-Si wafer of different structures diffused in same tube furnace. Except for diffusion, SiNx layers deposited on front surface for anti-reflecting. [pdf]

[FAQS about POLY 157 Daqo Group]
At the component level, polysilicon has long been used as the conducting gate material in and processing technologies. For these technologies it is deposited using low-pressure chemical-vapour deposition () reactors at high temperatures and is usually heavily doped or . More recently, intrinsic and doped polysilicon is being used in Polycrystalline solar cells are also called "multi-crystalline" or many-crystal silicon. Polycrystalline solar panels generally have lower efficiencies than monocrystalline cell options because there are many more crystals in each cell, meaning less freedom for the electrons to move.
