What is the value of eliminating the chamfer of mono silicon wafer/cell?
Today the chamfer of an M2 monocrystalline silicon wafer takes 0.56% of the whole area of the wafer. That is to say, if we produce a square monocrystalline silicon wafer, the total wafer area will increase 0.56%. According to the conversion efficiency of solar cells, the value of eliminating the […]
