2018-11-05T10:16:38Z terms-of-use Zuschlag, Annika The investigation of LeTID effects in mc-Si material requires repeated measurements of the minority charge carrier lifetime τ<sub>eff</sub>. Due to the inhomogeneous nature of mc-Si, measurements of τ<sub>eff</sub> should be carried out in a spatially resolved way. In this work, we show results for the impact of firing and gettering on LeTID in high quality mc-Si material and analyse them in terms of the effective defect density N<sub>eff</sub> while retaining the spatial information. We show that especially for low peak firing temperature degradation is not homogeneous and that firing and gettering influence the degree of spatial inhomogeneity. eng 2018 Hahn, Giso Firing and gettering dependence of effective defect density in material exhibiting LeTID Skorka, Daniel Hahn, Giso Skorka, Daniel Zuschlag, Annika 2018-11-05T10:16:38Z
