Probing of mechanical, optical and thermoelectric characteristics of double perovskites Cs2GeCl/Br6 by DFT method
TL;DR: The double perovskites halides are potential materials for renewable energy to meet the demands of the global energy shortage as discussed by the authors, and structural and thermodynamic stabilities of studied materials are ensured by the Goldsmith tolerance factor (0.86 and 0.91) and negative formation energy.

TL;DR: The distribution of octahedra types in mixed anion compounds was found to be consistent with a near-random distribution of halide anions throughout the structure, although some deviations from random halide distribution were noted in mixed iodide–bromide compounds, where the larger iodide anion preferentially adopted trans configurations.

TL;DR: It is a growing consensus that tin (Sn) is the best choice as Pb alternative over any other Pb-free metal elements and all-inorganic one is a promising candidate for PSCs owing to its more suitable bandgap, better stability, and higher charge mobility compared to the organic-in organic hybrid counterparts.

Enhanced Charge-Collection Efficiencies and Light Scattering in Dye-Sensitized Solar Cells Using Oriented TiO2 Nanotubes Arrays
TL;DR: Analysis of photocurrent measurements indicates that the light-harvesting efficiencies of NT-based DSSCs were higher than those found for D SSCs incorporating NPs owing to stronger internal light-scattering effects.
