Abstract The coffee‐ring effect, caused by uneven deposition of colloidal particles in perovskite precursor solutions, leads to poor uniformity films prepared through large‐area printing. In this work, the surface SnO 2 is roughened construct a Wenzel model, successfully achieving super‐hydrophilic interface. This modification significantly accelerates spreading solution, reducing response delay time during printing process. Additionally, micro‐spherical depression structure on effectively inhibits migration toward edges liquid film, trapping at buried interfaces and improving film uniformity. Due synergistic effect super‐hydrophilicity micro‐rough , leading substantial improvement quality crystals. Therefore, efficiency flexible devices (0.101 cm ) reached 25.42% (certified 25.12%). Moreover, rigid large‐scale solar modules (PSMs) based meniscus‐coating manufacture 21.34% 16.99% (100 ), respectively, demonstrated superior environmental stability maintaining an initial 91% after being stored atmospheric conditions for 2000 h, offering practical guidance fabricating high‐performance stable cells (PSCs).

Abstract Inverted perovskite solar cells (IPSCs) utilizing nickel oxide (NiO x ) as hole transport material have made great progress, driven by improvements in materials and interface engineering. However, challenges remain due to the low intrinsic conductivity of NiO inefficient transport. In this study, we introduced MoS 2 nanoparticles at indium tin (ITO) /NiO enhance ITO surface optimize deposition , resulting increased linked a ratio Ni 3+ :Ni 2+ . This modification not only optimized energy level but also promoted reduced defects. Consequently, IPSCs with modified ITO/NiO achieved champion power conversion efficiency (PCE) 21.42 %, compared 20.25 % without modification. Additionally, unencapsulated displayed improved stability under thermal, light, humidity ambient conditions. innovative strategy for efficiently promotes transportation can be integrated other engineering approaches, offering valuable insights development highly efficient stable IPSCs.

Perovskite solar cells (PSCs) based on single crystals hold potential for higher efficiency and stability, while the incomplete interface contact hinders hole carrier extraction device performance. Herein, we report strengthening crystal/substrate by nucleation engineering in situ growth strategy. Through modulating transport layer (HTL) to induce process at substrate surface, residual solution, voids, small-sized are eliminated, thus ensuring intimate physically. Combining with strong interaction between perovskites HTL, balanced electron/hole suppressed nonradiative recombination achieved. As a result, an impressive power conversion (PCE) of 25.8 % is obtained, setting new benchmark single-crystal PSCs. Moreover, thermal-induced peeling-off from substrates mitigated, which improves thermal stability distinctly.
