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 The efficiency loss caused by area scaling is one of the key factors hindering industrial development perovskite solar cells. energy and contact issues in buried interface are main reasons. Here, a new self‐assembled monolayer (SAM), Ph‐4PACz, with large dipole moment (2.32 D) obtained . It found that Ph‐4PACz high polarity can improve band alignment minimize , resulting an open‐circuit voltage ( V oc ) as 1.2 for 1.55 eV perovskite. However, when applied to large‐area devices, fill factor (FF) still suffered from significant attenuation. Therefore, alumina nanoparticles (Al 2 O 3 ‐NPs) introduced between rough FTO substrate further flatness conformal film almost no voids interface, thus promoting low exciton binding energy, fast hot‐carrier extraction non‐radiative recombination. final devices achieved small‐area power conversion (PCE) 25.60% (1 cm PCE 24.61% (certified at 24.48%), which represents highest single device ≥ 1 area. Additionally, mini‐modules stability testing also carried out demonstrate feasibility commercialization.

The efficiency and longevity of metal-halide perovskite solar cells are typically dictated by nonradiative defect-mediated charge recombination. In this work, we demonstrate a vapor-based amino-silane passivation that reduces photovoltage deficits to around 100 millivolts (>90% the thermodynamic limit) in bandgaps between 1.6 1.8 electron volts, which is crucial for tandem applications. A primary-, secondary-, or tertiary-amino-silane alone negatively barely affected crystallinity transport, but amino-silanes incorporate primary secondary amines yield up 60-fold increase photoluminescence quantum preserve long-range conduction. Amino-silane-treated devices retained 95% power conversion more than 1500 hours under full-spectrum sunlight at 85°C open-circuit conditions ambient air with relative humidity 50 60%.
