Off-axis holography on solar cell with CIGS of high Cu content. a, b Extracted phase images from off-axis holograms acquired on the solar cell that has an absorber layer with high Cu content. c HAADF-STEM and d BF-STEM micrographs show the same region of the solar cell. The line profiles that were extracted from the phase images and the HAADF-STEM image along the marked areas are given in Fig. 7
