Abstract/Summary:


In our work we aim to, with the help of numerical modelling on one side and subsequent correlation with spatially resolved measurements on the other, qualitatively evaluate and quantitatively determine the recombination parameters of cut edges of silicon solar cells, which govern the efficiency decreases of cut-cells obtained by different cell separation techniques (cleaving, laser ablation and cleaving, thermal laser separation). With the proposed approach, we were able to recreate an LBIC scan of a healthy part of a separated Zebra IBC cell in high detail.
