The cracks in crystalline silicon solar wafers can be categorized as either macro-cracks or micro-cracks, depending on their size. Cracks with a width of less than 30 μm are generally referred to as micro-cracks [5].The presence of micro-cracks in the silicon wafer not only increases the risk of wafer breakage during the fabrication process, but …
