摘要

Due to the multi-wire slurry sawing process, crystalline silicon wafers show a critical damage behavior in formof a limited breaking strength. To enhance the yield of the crystalline solar cell production, it is necessary to minimize thebreaking ratio of silicon wafers and solar cells. The breaking strength is determined both by the surface quality at the edges(especially determined by microcracks and chippings) and by the surface quality of the front and back sides of the wafer(especially determined by steps, grooves and microcracks). In our contribution we investigated the subsurface and edgedamages of selected multicrystalline silicon wafers and developed a special fracture bending test for investigating criticalwafer areas. This allows a correlation between space-resolved breaking strength values and corresponding surface roughnessand crack depths.
