From the Si ingots grown to the wafers which can be used to fabricate solar cells, excessive machining is required. The breaking of Si wafer and cracking of Si ingot directly lead to the waste of material cost. So, the diamond line slicing process determines the production cost of the entire Si solar cell industry.
Dislocation is a common extended defect in crystalline silicon solar cells, which affects the recombination characteristics of solar cells by forming deep-level defect states in the silicon bandgap, thereby reducing the lifetime of minority carrier.
