Abstract [4‐(3,6‐dimethyl‐9H‐carbazol‐9yl)butyl]phosphonic acid (Me‐4PACz) self‐assembled molecules (SAM) are an effective method to solve the problem of buried interface NiO x in inverted perovskite solar cells (PSCs). However, Me‐4PACz end group (carbazole core) cannot forcefully passivate defects at bottom film. Here, a Co‐SAM strategy is employed modify PSCs. doped with phosphorylcholine chloride (PC) form improve monolayer coverage and reduce leakage current. The phosphate ions (Cl − ) PC can inhibit surface defects. Meantime, quaternary ammonium Cl fill organic cations halogen vacancies film enable passivation. Moreover, promote growth crystals, collaboratively defects, suppress nonradiative recombination, accelerate carrier transmission, relieve residual stress Consequently, modified devices show power conversion efficiencies as high 25.09% well excellent device stability 93% initial efficiency after 1000 h operation under one‐sun illumination. This work demonstrates novel approach for enhancing performance PSCs by modifying on .

Printable mesoscopic perovskite solar cells (p-MPSCs) do not require the added hole-transport layer needed in traditional p-n junctions but have also exhibited lower power conversion efficiencies of about 19%. We performed device simulation and carrier dynamics analysis to design a p-MPSC with mesoporous layers semiconducting titanium dioxide, insulating zirconium conducting carbon infiltrated that enabled three-dimensional injection photoexcited electrons into dioxide for collection at transparent conductor layer. Holes underwent long-distance diffusion toward back electrode, this separation reduced recombination contact. Nonradiative bulk dioxide/perovskite interface was by ammonium phosphate modification. The resulting p-MPSCs achieved efficiency 22.2% maintained 97% their initial after 750 hours maximum point tracking 55 ± 5°C.

Abstract Inverted perovskite solar cells (PSCs) comprising formamidinium‐cesium (FA‐Cs) lead triiodide have garnered considerable attention due to their impressive efficiency and remarkable stability. Nevertheless, synthesizing high‐quality FA‐Cs alloyed films presents challenges, primarily attributable the intricate interphase process involved absence of methylammonium (MA + ) mixed halogens. Here, additive 3‐phosphonopropanoic acid (3‐PPA) is introduced, with bifunctional phosphonic groups, into precursor modulate crystal growth provide passivation at grain boundaries. In situ characterization reveals that 3‐PPA can form a “rapid nucleation, slow growth” mechanism, resulting in enlarged grains enhanced crystallinity. addition, serves passivate boundary defects release residual strain by forming molecular bridging, leading passivated achieving fluorescence lifetime 5.79 microseconds favorable n‐type contact interface. As result, devices incorporating achieve champion power conversion (PCE) 24.05% an ultra‐high fill factor (FF) 84.22%. More importantly, optimized exhibit satisfactory stability under various testing conditions. The findings underscore pivotal role multifunctional additives crystallization control defect for high‐performance MA‐free pure iodine PSCs.
