ABSTRACT Carbon‐based hole‐transport‐layer (HTL)‐free CsPbI 2 Br solar cells have attracted considerable interest due to the improved stability, simple structure, rich application scenarios, and low cost, as compared with their organic–inorganic hybrid counterparts. However, uncoordinated Pb 2+ mobile I − ions impose challenges for fabricating a cell good comprehensive performance. To address related issues, herein, we introduce facile additive strategy using an organic small molecule material, i.e., 1H‐imidazole‐4‐carboxylic acid (ICA), improve performance of carbon‐based HTL‐free cells. Benefitting from effective passivation anchoring , well increased crystallinity reduced surface roughness layers by ICA, optimal delivers power conversion efficiency (PCE) 14.71%, ⁓24.7% increment relative PCE 11.80% control device without ICA addition. Moreover, ICA‐added exhibits evidently hysteresis current–voltage characteristics notably enhanced in contrast device.

Photocatalytic technology offers significant advantages in addressing water pollution and energy regeneration challenges. Notably, photocatalytic CO2 reduction can convert into stable, efficient, clean carbon compounds such as monoxide, methane, ethylene, other high-value compounds, providing a novel approach to mitigating the global crisis maintaining balance. However, traditional semiconductor materials face limitations degradation due their low light utilization, severe photocorrosion, rapid photogenerated carrier recombination, slow electron transport rates. Recent studies have shown that introducing various effectively address these issues. Carrier materials, with unique properties, enhance composite photocatalyst systems, promoting separation improving utilization. This review introduces different used fabrication, systematically explains preparation strategies for carrier-based photocatalysts, summarizes applications. Finally, future developments this field are discussed. aims provide diverse designing leveraging special effects of control modes, interface behaviors, band structures.
