Abstract Metal halide perovskite solar cells (PSCs) have emerged as one of the most promising candidates for next‐generation photovoltaic technologies. However, films deposited by blade‐coating usually exhibit inferior film morphology compared to those fabricated spin‐coating, which hinders power conversion efficiency (PCE) and stability scalable modules (PSMs). Herein, ellipsoidal colloids are tailored in precursor solution incorporating polymer additives. Compared unregulated spherical colloids, demonstrate more oriented packing during process, is due anisotropic driven force from fluidic flow meniscus. As a result improved morphology, regulated PSCs PSMs achieve superior PCE 24.31% 21.67% (21.37% certified), respectively, aperture areas 0.09 13.94 cm 2 , 89% initial after 600 h continuous operation.

High-performance and cost-effective hole-collecting materials (HCMs) are indispensable for commercially viable perovskite solar cells (PSCs). Here, we report an anchorable HCM composed of a triazatruxene core connected with three alkyl carboxylic acid groups (3CATAT-C3). In contrast to the phosphonic acid-containing tripodal analog (3PATAT-C3), 3CATAT-C3 molecules can form hydrophilic monolayer on transparent conducting oxide surface, which is beneficial subsequent film deposition in traditional layer-by-layer fabrication process. More importantly, larger diffusion coefficient higher surface energy make suitable simplified, one-step co-deposition process was directly added as part precursor solution. predominantly located at bottom after spin-coating mixed solution, facilitating charge extraction. Devices fabricated by this method exhibit superior performance champion power conversion efficiency over 23%. The unencapsulated devices showed good operational stability (retaining 90% initial output 100 h), thermal durability 95% value heating 105 °C under air), excellent storage (showing no drop 8000 h).

Abstract Perovskite solar cells (PSCs) have garnered significant attention for their outstanding optoelectronic properties, yet surface defects remain a major obstacle to achieving optimal performance, especially in scalable hybrid evaporation‐solution fabrication methods. Conventional passivation techniques often struggle with shallow penetration of agents, limiting effectiveness. Here, an advanced post‐treatment strategy is introduced that synergistically combines 2‐thiopheneethylammonium chloride trace amount ethylenediamine achieve superior passivation. acts as “penetration facilitator,” mildly etching the perovskite and enabling deeper infiltration chloride, which results formation uniformly distributed pure‐phase 2D layer. This deeply penetrating layer effectively suppresses nonradiative recombination at perovskite/electron transport interface. As result, inverted PSCs fabricated using method achieved power conversion efficiency 24.20%, accompanied by open‐circuit voltage 1.189 V deficit 0.36 V. Additionally, this demonstrates broad performance enhancements across various bandgaps methods, offering versatile promising pathway boost both stability PSCs.

Abstract Metal halide perovskites are ideal candidates for indoor photovoltaics (IPVs) due to their tunable bandgaps, which allow the active layers be optimized artificial light sources. However, significant non‐radiative carrier recombination under low‐light conditions has limited full potential of perovskite‐based IPVs. To address this challenge, an integration perylene diimide (PDI)‐based sulfobetaines as cathode interlayers (CILs) is proposed and impact varying alkyl chain length (from 1,2‐ethylene 1,5‐pentylene) between cationic anionic moieties examined. The respective four PDI materials synthesized almost qualitatively using a one‐step microwave‐assisted process. All them show adequate thermal stability energy levels suitable desired application CILs. Moreover, degradation temperature, LUMO level, conductivity, performance in model devices found change positively along with increase.
