Perovskite solar cells (PSCs) have demonstrated remarkably rapid efficiency improvements mainly through spin-coating-based solution processes. While these processes offer numerous advantages, there are also several limitations, prompting research into alternative fabrication methodologies for PSCs. Meanwhile, surface engineering has been identified as one of the most critical factors enhancing and stability For passivation, studies reported to date, especially n–i–p structures, relied on solution-based However, face challenges in controlling termination perovskite surfaces, achieving fine thickness control, dealing with lead halides that utilize common solvents perovskites. In this study, we introduce a strategy employing dry-vacuum deposition process deposit PbI2 PbCl2 nanoscale precision thin films. This is followed by vacuum alkyl (4-methoxy-phenethylammonium-iodide, MeO-PEAI), which improved photostability devices compared typical solution-processed MeO-PEAI treatment.

Suppressing deep-level defects at the perovskite bulk and surface is indispensable for reducing non-radiative recombination losses improving efficiency stability of solar cells (PSCs). In this study, two Lewis bases based on chalcogen-thiophene (n-Bu4S) selenophene (n-Bu4Se) having tetra-pyridine as bridge are developed to passivate in film. The uncoordinated Pb2+ iodine vacancy can interact with chalcogen-concave group pyridine through formation acid-base adduct, particularly both be surrounded by concave molecules, resulting effective suppression charge recombination. This approach enables a power conversion (PCE) high 25.37% (25.18% certified) n-i-p PSCs stable operation 65 °C 1-sun illumination 1300 hours N2 (ISOS-L-2 protocol), retaining 94% initial efficiency.

Commercial SnO2 nanocrystals used for producing electron transporting layers (ETLs) of perovskite solar cells (PSC) are prone to aggregation at room temperature and contain many structural defects. Herein, we report that the LiOH additive can simultaneously delay donate beneficial aging effect nanocrystals. The resulting ETLs show desired characteristics, including a broadened absorption range, reduced defects, improved properties, decreased work function. Meanwhile, Cs0.15FA0.65MA0.20Pb(I0.80Br0.20)3 films with wide bandgap 1.68 eV grown on them exhibit pure phase, higher crystallinity, fewer better buried-interface contact, more aligned energy levels each other than ones based without treatment. Hence, average efficiencies boosted from (18.79 ± 0.40)% (20.16 0.36)% wide-bandgap PSCs, wherein champion efficiency 21.12% is achieved. In addition, as-obtained PSCs possess good thermal humidity stability.

Abstract Tin oxide (SnO 2 ) with high conductivity and excellent photostability has been considered as one of the most promising materials for efficient electron transport layer (ETL) in perovskite solar cells (PSCs). Among them, SnO nanoparticles (NPs) dispersions have extensively utilized due to their facile film formation. However, inherent defects agglomeration issues NPs, well limited tunability instability post‐treatment process surface/interface engineering strategy, still hinder its further applications. Herein, a ligand‐management strategy implemented during situ synthesis NPs that can effectively achieve uniform modification is proposed. During grafting reaction between diethyl 2‐chloromalonate (DCMA) surface completed. Compared process, this intrinsic DCMA‐passivated (DCMA‐SnO reduces trap state density at interface ETL while enhancing chemical stability. Consequently, PSCs based on DCMA‐SnO champion PCE 25.39% small (active area 0.0655 cm 20.61% modules 23.25 ), demonstrating shelf‐life/light soaking stability (advanced level ISOS protocols). This exhibits significant application potential preparing high‐efficiency large‐area PSCs.
