“…Alternatively, 2D perovskites may be more promising for their incorporation in practical devices due to their long, hydrophobic alkyl chain cations. 2–4 The general formula of these organic–inorganic hybrids is (R-NH 3 ) 2 PbX 4 where R is a long-chain alkylammonium cation, and X is a halide. These perovskites consist of two-dimensional sheets of the corner-sharing octahedral anions [PbX 6 ] 4− capped with alternating double layers of cations (C n H 2 n +1 NH 3 ) + , which are stabilized by hydrogen bonding between ammonium cations and halides in the inorganic layers.…”

Directly capturing water from the air has become a compelling strategy to secure water resources. Yet, challenges persist with sorption‐based hygroscopic materials, such as inadequate water adsorption efficiency, material degradation post‐adsorption, and the need for energy input during water collection. This study introduces an alternative category of sorbent materials potentially for atmospheric water harvesting—metal chloride perovskites—that exhibit spontaneous water vapor adsorption and liquid water collection. This water uptake capability stems from the uncoordinated polar ions that form hydrogen bonds with water molecules, while the cubic lattice imparts a solid framework ensuring structural stability and inhibiting hydrolysis. The methylammonium lead chloride perovskite pellets exhibit efficient water collection performance, with a record absorption rate of 0.841 L m−2 h−1 and a total water collection of 3.675 L m−2 within a 7‐h cycle. This initiative attempts to provide a new material class candidate for the potential application of passive atmospheric water harvesting.

Halide perovskite solar cells have achieved impressive efficiencies above 26%, making them a promising technology for the future of solar energy. However, the current fabrication methods rely on highly toxic solvents, which pose significant safety and environmental hazards. It is crucial to develop greener and safer alternatives to these solvents to facilitate the commercialization of perovskite solar cells. In this review, the safety and hazard evaluations of conventional toxic solvents and discuss the selection criteria for solvents that affect the morphology, nucleation, crystallization, and performance of perovskite solar cells. Furthermore, recent research into green solvent alternatives is evaluated and their properties are compared to those of commonly used solvents. In this review, fundamental insights are provided into the progress and challenges of green‐solution processing of perovskite solar cells, which will be essential for advancing this technology toward commercialization.
