Its low yield is mainly restricted by poor reactant activation efficiency, mismatched reaction kinetics, slow C─N coupling and slow gas mass transfer via water hydrogen bond networks. Herein, an external magnetic field was adopted to boost photocatalytic urea synthesis. Upon magneto-photocatalysis, water hydrogen bonds were disturbed to form gas diffusion channel and release sufficient hydrogen protons.

However, SnO<sub>2</sub> films from the conventional chemical bath deposition (CBD) are limited by impurities and defects that accelerate non-radiative recombination and compromise device stability. Here, we present a volatile additive engineering strategy using pyruvic acid (PA) as a dual-functional nucleation promoter and surface modulator during SnO<sub>2</sub> deposition. Owing to its volatility (sublimation at 145°C), PA can be effectively removed during annealing, resulting in cleaner SnO<sub>2</sub> surfaces with reduced residual groups. This is accompanied by a decrease in oxygen-related defect densities in the SnO<sub>2</sub> layer. This improvement leads to enhanced charge recombination and improved thermal stability at the buried interface. Consequently, PA-engineered PSCs achieve a power conversion efficiency of 26.17%, together with improved device stability, retaining >80% of their initial efficiency after 900 h of continuous operation, 1000 h at 65°C, and 30 days under 30% relative humidity.

These are often treated as competing frameworks for the interpretation of seemingly similar experimental observations. Here, we argue that progress in the field is limited due to an intertwining of kinetic and thermodynamic aspects of segregation and encourage the use of a generalized thermodynamic description in which different microscopic models correspond to different ways of modifying the free-energy balance under illumination. We therefore analyze the assumptions, predictions, and experimental signatures of the most widely discussed mechanisms.
