TL;DR: It is demonstrated that the substitution of methylammonium with the formamidinium cations inside the in organic cage gives greater robustness to the overall lattice and extends the material durability due to a different interaction between the organic molecules and the inorganic cage, which supports the use of FAPbI3 in applications, provided its structure can be stabilized in the dark phase at room temperature.

TL;DR: The cross-correlation of optical data with DFT calculations evidences the role of octahedral tilting in tailoring the value of the band gap at a given temperature, whereas differences in the thermal expansion affect the slope of theBand gap trend as a function of temperature.

TL;DR: It is reported that, in a polycrystalline MAPbI3 layer, Pb-related defects aggregate into nanoclusters preferentially at the triple grain boundaries as unveiled by Transmission Electron Microscopy (TEM) analyses at low total electron dose.

TL;DR: A critical analysis of the available data indicates that degradation under ambient conditions is a defect-generation process that is highly localized on surfaces and interfaces, while it is further enhanced above the tetragonal-cubic transition at ∼54 °C.

TL;DR: It is shown that the SBH of multilayer MoS2 surface can be tailored at nanoscale using soft O2 plasma treatments and can be conveniently tuned starting from a narrow SBH distribution to a broader distribution after 600 s O1 plasma treatment, which allows both electron and hole injection.
