A phase microscope for quantum gases

Coherence properties are central to quantum systems and are at the heart of phenomena such as superconductivity. In this work, we studied coherence properties of an ultracold Bose gas in a two-dimensional optical lattice across the thermal phase transition. To infer the phase coherence and phase fluctuation profiles, we used direct matter-wave imaging of higher Talbot revivals and introduced a phase microscope based on a site-resolved mapping of phase fluctuations to density fluctuations during matter-wave imaging. We observed the algebraic decay of the phase correlations in the superfluid phase and a linear temperature increase of the exponent. These techniques may enable studying coherence properties in strongly correlated quantum systems with full spatial resolution.

Indium-free perovskite/silicon tandem solar cells with tin oxide recombination layer and electrodes

Indium-based transparent conductive oxides are widely used as electrodes and recombination layers in perovskite/silicon tandem solar cells, yet their scalability is constrained by indium scarcity and sputtering-induced damage. We report high-efficiency and stable indium-free perovskite/silicon tandem solar cells enabled by reactive plasma deposited tin oxide (RPD-SnO x ). For RPD-SnO x as the recombination layer, we achieved a certified efficiency of 33.6%. Fully indium-free tandems that used RPD-SnO x as both recombination layer and electrodes delivered a champion power conversion efficiency of 33.2% (1 square centimeter) and a minimodule with a certified efficiency of 31.0% (207.9 square centimeters). Dense and uniform self-assembled monolayer anchoring enabled by RPD-SnO x suppressed nonradiative recombination and reduced halide migration. Indium-free minimodules exhibited high thermal, damp-heat, and outdoor operational stability and retained 65% of their maximum initial efficiency after 105 days of outdoor operation.
