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.

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.

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.
