EDX investigation of the material composition in the P3 scribe lines as a function of the applied laser fluence. The blue triangles represent elemental Pb (M line) and the blue open circles represent elemental Zn (L line), which are indicators for the perovskite absorber and the intermediate window layer stack, respectively. The elemental Cu (L line) signal is represented by black squares and is used as an indicator for the CIGSe absorber (right y axis). The selected fluence is marked with an asterisk.
