Defect related luminescence (DRL) of mc-Si wafers, including the four D line emissions D1-D4, is investigated by hyperspectral photoluminescence (PL) imaging. The background subtraction scheme for the hyperspectral imaging setup is improved in order to obtain enhanced possibilities for comparing the DRL of different samples. In combination with PL based techniques for lifetime and iron imaging, the improved hyperspectral imaging technique is used to compare DRL of n type and p-type mc-Si material, and to study changes of the DRL spectrum along the height of a crystalline ingot. Further, the correlation between DRL and metallic impurities as well as changes of DRL due to solar cell processing steps are investigated. No differences in the D l...
