This dual functionality enables simultaneous passivation surface defects both buried layers. In addition, electron‐deficient nature enhances energy band alignment facilitates transfer from . Furthermore, incorporation strengthens adhesion, improving mechanical reliability. As result, PSCs exhibited impressive power conversion efficiency (PCE) 25.41 % under standard AM 1.5G conditions, along remarkable environmental stability.

Abstract The past decade has witnessed the rapid increasement in power conversion efficiency of perovskite solar cells (PSCs). However, serious ion migration hampers their operational stability. Although dopants composed varied cations and anions are introduced into to suppress migration, impact or is not individually explored, which hinders evaluation different further application doping strategy. Here we report that a special group sulfonic (like CF 3 SO − ) successfully introduce alkaline earth ions Ca 2+ lattice compared its halide counterparts. Furthermore, with effective crystallization regulation defect passivation anions, Ca(CF 2 shows reduced PbI residue metallic Pb 0 defects; thereby, corresponding PSCs show an enhanced PCE 24.95%. Finally by comparing properties FACF , found doped significantly suppressed activation energy 1.246 eV accounts for improved stability -doped PSCs, while no obvious on trap density observed.

Abstract Molecular bridges with one end absorbed on the electron transport layer (ETL) and other bound to perovskite can effectively repair imperfections at ETL/perovskite interface. However, single‐layered usually coexist undesired double‐layered molecules, leaving a Van der Waals gap between them. Charge only occur via tunneling effect travel through gap, which requires forward voltage bias leads constrained charge efficiency. Herein, study designs synthesizes an imidazolium derivative ionic salt of 1,3‐dibenzyl‐2‐phenylimidazolium chloride (DPhImCl), featuring multiple aromatic side chains, form bilayered interfacial molecular mediated by π–π stacking. The reveals that DPhIm + strongly adsorbs both SnO 2 surfaces ring, while two layers respectively interact stacking benzene ring in forming bridge /perovskite This interaction promotes orderly creates hopping channels for transport, thus facilitating transfer As result, impressive device efficiency 25.90% (certified 25.27%) robust T 90 operational lifetime 1101 h n‐i‐p solar cells achieved.

Environmentally friendly antisolvents are key to achieving efficient, reproducible, and sustainable perovskite solar cells (PSCs). Here, a comparison was made between the traditional highly toxic chlorobenzene (CB) antisolvent green ethyl acetate (EA) dimethyl carbonate (DMC). The employment of DMC shown result in formation films with enhanced grain size superior crystal quality. This leads an optimal energy level alignment electron transport layer, effectively mitigating nonradiative recombination caused by film imperfections, reducing loss organic components during annealing process, suppressing lead iodide phase. Finally, champion device, based on DMC, exhibited high power conversion efficiency (PCE) 25.18%, which is one PCEs reported for this device structure. Moreover, maintains 92% its original PCE after approximately 1000 h under environmental conditions.
