Abstract: Abstract In order to reduce the cost per watt of photovoltaic power generation, reducing the thickness of the crystalline silicon solar cell is a promising strategy. However, with a thinner silicon wafer, the bowing depth induced by two distinctive thermal expansion rates between the silicon substrate and the aluminum layer in the rear side grows exponentially. Excessive bowing can cause damage such as breakage and microcracks to the silicon wafer, eventually resulting in ruining the cell. The detail understanding of the bow phenomenon is undou...
