I believe that many people are not very familiar with the terms of some monocrystalline silicon chips, polycrystalline silicon chips, modules, solar panels, 8 awg pv wire, solar cell chips, and what is the relationship between them?
Monocrystalline silicon: It is the raw material of the battery sheet, the upstream of the industrial chain, and the silicon element is obtained by lowering silicon dioxide, and the silicon purity is 80%.
Silicon INgot: including monocrystalline silicon ingot, they need to use different purification methods, monocrystalline silicon ingot with pulling method, polycrystalline silicon ingot casting method, the purity of 99.99%.
Silicon wafer: Also includes single polycrystalline silicon wafer, diamond wire or other methods to chop silicon ingot into regular shape. There are also different specifications of mono-polycrystalline cells (125*125mm, 156*156mm, etc.)
Solar cell sheet: The single polycrystalline silicon sheet is converted into a semiconductor device that can generate voltage and current under light after several steps, such as cleaning, fluxing, diffusion, deposition of antireflective film, wire screen printing of metal electrodes, and high temperature sintering.
Solar panel: surface material (PET/ETFE/ glass, etc.) +EVA+ solar cell +EVA+ backplane (TPT/PCB/PET, etc.) for packaging.
Solar panels: Also called solar panels, but normally have more bezels, junction boxes, and other accessories than solar panels.
Solar photovoltaic power station: the general power will be massive, more than 300-400W.
