Inhomogeneities and defects often limit the overall performance of thin-film solar cells. Therefore, sophisticated microscopy approaches are sought to characterize performance and defects at the nanoscale. Here, we demonstrate, for the first time, the simultaneous assessment of composition, structure, and performance in four-fold multi-modality. Using scanning X-ray microscopy of a Cu(In,Ga)Se2 (CIGS) solar cell, we measured the elemental distribution of the key absorber elements, the electrical and optical response, and the phase shift of the coherent X-rays with nanoscale resolution. We found structural features in the absorber layer—interpreted as voids—that correlate with poor electrical performance and point towards defects that limit the overall solar cell efficiency.

“…The polyimide foil with the copper(I) oxide particles on both sides was glued to a thin silicon frame, covering a hole of diameter. The plate with the foil on top was clamped into a sample holder, which was placed inside the PtyNAMi setup 46 , 47 . The X-ray beam coming from the undulator was monochromatized to using a Si-(111) double-crystal monochromator.…”

Ptychographic X-ray microscopy is an ideal tool to observe chemical processes under in situ conditions. Chemical reactors, however, are often thicker than the depth of field, limiting the lateral spatial resolution in projection images. To overcome this limit and reach higher lateral spatial resolution, wave propagation within the sample environment has to be taken into account. Here, we demonstrate this effect recording a ptychographic projection of copper(I) oxide nanocubes grown on two sides of a polyimide foil. Reconstructing the nanocubes using the conventional ptychographic model shows the limitation in the achieved resolution due to the thickness of the foil. Whereas, utilizing a multi-slice approach unambiguously separates two sharper reconstructions of nanocubes on both sides of the foil. Moreover, we illustrate how ptychographic multi-slice reconstructions are crucial for high-quality imaging of chemical processes by ex situ studying copper(I) oxide nanocubes grown on the walls of a liquid cell.

“…High spatial resolution and large sample penetration depth allow for detailed studies of volume samples, often in their close to natural state. Instrument and method development is rapid and most low-emittance synchrotron facilities are today operating or developing one or several hard X-ray nanoprobe beamlines (Leake et al, 2019;Holler et al, 2018;Chang et al, 2013;Chen et al, 2014;Martı ´nez-Criado et al, 2016;Nazaretski et al, 2017;Quinn et al, 2021;Schropp et al, 2020;Somogyi et al, 2015;Tolentino et al, 2017;Winarski et al, 2012;de Jonge et al, 2014). A number of technology developments have been important to make SXM attractive to a broader community.…”

NanoMAX is the first hard X-ray nanoprobe beamline at the MAX IV laboratory. It utilizes the unique properties of the world's first operational multi-bend achromat storage ring to provide an intense and coherent focused beam for experiments with several methods. In this paper we present the beamline optics design in detail, show the performance figures, and give an overview of the surrounding infrastructure and the operational diffraction endstation.
