TL;DR: Lin et al. as discussed by the authors used metallic tin to prevent oxidation in mixed Pb-Sn narrowbandgap perovskites to reduce the Sn4+ (an oxidation product of Sn2+) to Sn2+ via a comproportionation reaction.

TL;DR: Xiao et al. as mentioned in this paper used strongly reductive surface-anchoring zwitterionic molecules to suppress Sn2+ oxidation and passivate defects at the grain surfaces in mixed lead-tin perovskite films, enabling an efficiency of 21.7% (certified 20.7%).

TL;DR: An ammonium-cation-passivated Pb-Sn perovskites with long diffusion lengths are developed, enabling subcells having an absorber thickness of ~1.2 μm, and a certified efficiency of 26.4% in all-perovskite tandem solar cells is reported, exceeding that of the best-performing single-junction perovSKite solar cells.

TL;DR: In this article, a 3D artificial transpiration device with all three components of heat loss and angular dependence of light absorption minimized, which enables over 85% solar steam efficiency under one sun without external optical or thermal management.

TL;DR: In this paper, a carbon foam with a three-dimensional interconnected porous structure enables sufficient diffusion of vapor with a convective flow and therefore realizes an evaporation rate as high as 10.9
