[0002] At present, most photovoltaic companies have different degrees of demand for re-cutting of single crystal silicon rods in their machining workshops, which are mainly used for cutting and slicing of unprocessed short rods and re-cutting and slicing of standard round rods after truncation. With the increase in market demand for N-type wafers, the output ratio of N-type single crystal silicon rods of most photovoltaic companies has increased.
