In this study, the strategic incorporation of chiral graphene quantum dots (GQDs) at the PSC interface is pioneered, significantly mitigating these losses through this chiral interface engineering. Also in this study, by synthesizing and characterizing the chiroptic behavior and doping effects of both chiral and racemic GQDs, their pivotal role in enhancing charge extraction and transport is unveiled. In the findings of this study, it is shown that GQDs do not alter the crystallization of perovskite films but significantly boost light absorption owing to improved interfacial contact. Subsequent optical and electrical assessments reveal that the PSCs treated with chiral GQDs outperform those with racemic GQDs, primarily on account of the chiral specificity of chiral GQDs, which leads to reduced nonradiative recombination and enhanced charge transport efficiency.

Herein, a triple-layered aerogel-based solar evaporator with low-tortuosity pore structures (Tri-ASEL) is constructed. Benefiting from the unique pore structures of Tri-ASEL, it not only exhibits excellent water transport capacity, which is significantly increased by 237.5% compared to that of the aerogel-based solar evaporator with uniform pore structures, but also effectively reduces the downward heat transfer owing to the low thermal conductivity of the top layer. Meanwhile, compared with the aerogel-based solar evaporator with triple-layered pore structures (Tri-ASE), Tri-ASEL can reduce the resistance of ion diffusion and shorten the diffusion pathways through the low-tortuosity pore structures. Because of the effective coordination of the contradiction among the water transport, ion diffusion, and thermal insulation, Tri-ASEL achieves a high evaporation rate of 2.803 kg m<sup>−2</sup> h<sup>−1</sup> and exhibits a remarkable evaporation efficiency of 97.95% under 1 sun.
