EDX investigation of the material composition in the P2 scribe lines as a function of the applied laser fluence. The blue triangles correspond to elemental Pb (M line) used as indicator for the perovskite absorber (left y-axis). The black squares refer to elemental Cu (L line), which corresponds to the underlying CIGSe absorber (right y-axis). The selected fluence is marked with an asterisk.
