Antisolvent treatment has been developed to effectively fabricate dimethyl ammoniumiodide (DMAI)assisted CsPbI 3 perovskite solar cells (PSC) under moisture conditions. However, a clear understanding of its effect on the crystallization mechanism is still elusive. Here, the antisolvent bathing effect on DMAIassisted CsPbI 3 crystallization is investigated under ambient condi tions. For films bathed into antisolvents with Lewis basic oxygen (i.e., diethyl ether, anisole, ethyl acetate, and methyl acetate), rapid crystallization kinetics are observed due to the interaction between Cs 4 PbI 6 and antisolvent in the form of the adduct. The Cs 4 PbI 6 antisolvent adduct lowers the transformation energy barrier, thereby enabling immediate phase transformation to CsPbI 3 as soon as DMAPbI 3 is decomposed. Based on this observation, a new crystal lization mechanism is proposed for DMAIassisted CsPbI 3 in which Cs 4 PbI 6 , instead of DMAPbI 3 , plays the role of the predominant phase of crystalliza tion. Accelerated crystallization due to anisole antisolvent bathing results in a uniform film morphology and better coverage with fewer defects and pinholes. This enhances the power conversion efficiency of the nipstruc tured PSCs based on anisolebathed CsPbI 3 to 18.84%, even under moisture conditions.

Due to their intrinsic spin control capability and excellent catalytic activity, chiral inorganic materials have been recognized as promising candidates for achieving a breakthrough in the solar-to-hydrogen efficiency of water-splitting...

Correction for ‘Elucidating the chirality transfer mechanisms during enantioselective synthesis for the spin-controlled oxygen evolution reaction’ by Hayoung Im et al., Energy Environ. Sci., 2023, 16, 1187–1199, https://doi.org/10.1039/D2EE03853F.

To realize practical solar hydrogen production, a low‐cost photocathode with high photocurrent density and onset potential should be developed. Herein, an efficient and stable overall photoelectrochemical tandem cell is developed with a Cu3BiS3‐based photocathode. By exploiting the crystallographic similarities between Bi2S3 and Cu3BiS3, a one‐step solution process with two sulfur sources is used to prepare the Bi2S3–Cu3BiS3 blended interlayer. The elongated Bi2S3‐Cu3BiS3 mixed‐phase 1D nanorods atop a planar Cu3BiS3 film enable a high photocurrent density of 7.8 mA cm−2 at 0 V versus the reversible hydrogen electrode, with an onset potential of 0.9 VRHE. The increased performance over the single‐phase Cu3BiS3 thin‐film photocathode is attributed to the enhanced light scattering and charge collection through the unique 1D nanostructure, improved electrical conductivity, and better band alignment with the n‐type CdS layer. A solar‐to‐hydrogen efficiency of 2.33% is achieved under unassisted conditions with a state‐of‐the‐art Mo:BiVO4 photoanode, with excellent stability exceeding 21 h.
