Summary: A binary antisolvent bathing approach was proposed for the formation of large-area perovskite solar cells with excellent power conversion efficiency. This method slowed down the crystallization process, resulting in enlarged perovskite crystals with highly preferential orientation alignment, improving charge extraction and reducing non-radiative recombination. The photovoltaic performance was significantly enhanced, and the binary antisolvent approach allowed for rapid elimination of residual antisolvent, enabling the fabrication of uniform large-area PSCs.

Summary: Chiral inorganic materials have shown promise in improving the efficiency of solar-to-hydrogen conversion in water-splitting devices due to their spin control capability and catalytic activity. However, a rational design for these materials in photoelectrochemical water-splitting is lacking. In this study, we investigated chirality transfer phenomena at the molecular level and found that chiral ligand molecules exhibit direction-dependent dimer interactions in the precursor solution, affecting chirality transfer and material quality. Based on this understanding, we successfully fabricated a chiral inorganic material-based water-splitting device with outstanding oxygen evolution reaction performance, demonstrating the great potential of chirality-induced spin-selectivity in the water-splitting process.
