P2 scribe line depth (right y-axis, black squares) and electrical resistance across the scribe line (left y-axis, blue squares) as a function of the applied laser fluence. The range of suitable fluences is marked by the light green area, the selected fluence with an asterisk. The brownish area illustrates the perovskite layer, the cyan area refers to the window layer stack, and the dark red area refers to the CIGSe absorber layer.
