However, low mechanical energy conversion efficiency and constrained surface active sites hinder its practical application.

The carbon vacancies and oxygen doping cause the formation of asymmetric structure of triazine unit with a strong dipole field, which creates spontaneous polarization field to speed up directional electron transfer to the nitrogen active sites for effective piezo-photocatalysis.

Regulating the thermal conductivity of halide perovskites by additive engineering is now a mainstream strategy for achieving self-cooling devices, but our fundamental understanding of how perovskites with atomic disorder function remains insufficient. This theoretical study unveils the underlying mechanism of facet-dependent thermodynamic properties in mixed-cation perovskites. The results demonstrate that the (100) facet has higher thermal conductivity than the (110) and (111) facets. By carefully controlling the (100) crystallographic orientation through buried and bulk modification, the thermal conductivity of the target perovskite film can be increased from 1.005 to 1.068 W m<sup>−1</sup> K<sup>−1</sup>, which lowers the PSC's equilibrium temperature 5.25 °C by accelerating heat transport and dissipation. Consequently, we achieve an inverted PSC with an excellent efficiency of 25.12%, accompanied by a significantly reduced temperature coefficient and better long-term stability: a conservation rate exceeding 90% after aging at 85 °C and exposure to persistent light irradiation for 1100 h.

Structure designs, including constructing architectural Li anode, three-dimension (3D) structure OSEs and integrated cathode can significantly increase the effective contact area between electrodes and OSEs to facilitate the interfacial ion transport. The interfacial modifications are utilized to improve the wettability of OSEs for lithium metal anode, enhance the interfacial ion transport, and stabilize the OSEs/electrodes interface.
