  • Mechanical fatigue occurs under cyclic stress much lower than the tensile strength, but this has not been investigated for 2D materials. Here, graphene is found to have a fatigue life of 109 cycles.

  • Because open-circuit voltage deficit is greater in wide-bandgap perovskite solar cells, the authors introduce diammonium molecules to modify perovskite surface states and achieve a more uniform spatial distribution of surface potential, enabling record voltage all-perovskite tandem solar cells.

  • Many best-performing perovskite photovoltaics use 2D/3D interfaces to improve efficiency and stability, yet the mechanism of interface assembly is unclear. Here, Proppe et al. use in-situ GIWAXS to resolve this transformation, observing progressive dimensional reduction from 3D to 2D perovskites.

  • Here, the authors utilise a combination of quasi-spherical theory and Jahn-Teller distortion to enhance the piezoelectric response of molecular metal halides, and the resulting piezoelectric energy harvesters exhibit superior power densities to the best-reported molecular hybrid energy harvesters.
