Passivating the defective surface of perovskite films is becoming a particularly effective approach to further boost efficiency and stability their solar cells. Organic ammonium halide salts are extensively utilized as passivation agents in form corresponding 2D perovskites construct 2D/3D bilayer architecture for superior device performance; however, this partly suffers from postannealing-induced destructiveness 3D bulk charge transport barrier induced by quantum confinement existing...
Abstract Significant advancements in perovskite solar cells (PSCs) have been driven by the engineering of interface between absorbers and charge transport layers. Inverted PSCs offer substantial potential with their high power conversion efficiency (PCE) enhanced compatibility for tandem cell applications. Conventional hole materials like poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) poly(triaryl amine) (PTAA) not only constrain PSC but also elevate fabrication costs. In...
Abstract Pure‐phase α‐FAPbI 3 quantum dots (QDs) are the focus of an increasing interest in photovoltaics due to their superior ambient stability, large absorption coefficient, and long charge‐carrier lifetime. However, trap states induced by ligand‐exchange process limit photovoltaic performances. Here, a simple post treatment using methylamine thiocyanate is developed reconstruct FAPbI ‐QD film surface, which MAPbI capping layer with thickness 6.2 nm formed on top. This planar perovskite...
Incorporating alkylammonium cations atop the 3D perovskite enables effective defect passivation and significantly enhances power conversion efficiency of solar cells. However, diversity durability this strategy have been limited to ligand type diffusion ligands due high reactivity. Here, we designed bulky "T-shaped" conjugated carbazole with inner π–π interaction enlarged steric hindrance minimize while maintaining effects.

The modification with 4-iodophenylboronic acid (4-IPBA) is optimal due to the strongest coordination Ni vacancies and best energy level alignment perovskite.
Drop‐on‐demand inkjet‐printing has the advantages of high cost‐effectiveness and powerful patterning ability, which can be a promising technique for perovskite pattern deposition. However, by far most reported works using films fabrication are printing solvent‐rich wet precursor layers on high‐temperature meso‐TiO 2 substrate, subsequently require vacuum‐assisted thermal annealing process to enhance crystallization precursor, largely elevates cost complexity. Herein, heat‐assisted is...
Abstract The interface of organic solar cells plays a crucial role in device performance and stability. Several investigations demonstrated that the will affect morphology microstructure active layer, which is important for performance. Here, several mercaptan derivatives are explored green‐solvent based (PBDB‐TF‐T1: BTP‐4F‐12) as effective stabilization modifiers on ZnO. Operando grazing‐incidence wide/small‐angle X‐ray scattering (GIWAXS/GISAXS) provides deep understanding degradation...
Solid additives have garnered significant attention due to their numerous advantages over liquid additives. This study explores the potential of green-fluorescent conjugated polymer denoted Atums Green as a solid additive in green-solvent-based PBDB-TF-T1:BTP-4F-12 solar cells. Even tiny amounts doping significantly improve device performance. For reference cell without any additive, we find that degradation is not caused by chemical redox reactions but changes crystallinity and...
