Experimental Study on Surface Integrity of Solar Cell Silicon Wafers

For solar cells, a longer minority carrier lifetime of the silicon wafer corresponds to a high photoelectric efficiency of the cell. Does the hybrid manufacturing method have any negative impacts on the minority carrier lifetime? Here, the minority carrier lifetime of wafers sliced by EMWS is measured using WT-2000 before and after texturing
