Low-bandgap (LBG) mixed tin-lead (Sn-Pb) perovskite solar cells (PSCs) suffer from inferior performance due to their high defect density. Conventionally, ethylenediammonium diiodide (EDADI) is used as a surface passivator reduce defects and improve device photovoltaic performance, but it introduces severe hysteresis caused by excessive mobilized ions at the top interface. Here, we report mobile ion suppressing strategy of using hydrazine monohydrochloride (HM) bulk anchor free in LBG perovskites. The protonated (N2H5+) HM formed hydrogen bonds with iodine (I-) ions, while chloride (Cl-) occupied I- vacancies, collectively impeding migration thus mitigating movement-induced that arose EDADI usage. synergistic doping post-treatment significantly suppresses oxidation Sn2+, decreases trap density, inhibits rapid crystallization perovskite. Consequently, achieved champion efficiency 23.21% for PSCs. Integrating these wide-bandgap PSCs into all-perovskite tandem yields 28.55% (certified 28.31%) negligible hysteresis.

Most high-efficiency all-perovskite tandem solar cells use a "superstrate" configuration, integrating wide-bandgap (WBG) top subcell and narrow bandgap (NBG) bottom subcell. However, this structure suffers oxidative degradation due to easily air-exposable NBG subcells. A "substrate" offers improved stability for tandems by encapsulating the with air-stable WBG conventional perovskite (PSCs) using water-based NiOx interlayers hinder their fabrication on of subcells in an inert atmosphere. To overcome this, we developed nonaqueous nanoparticle dispersion, enabling interlayer inside glove box. The blade-coated facilitated formation densely packed 2PACz (2-(9H-carbazol-9-yl)ethyl]phosphonic acid) monolayer hole transporting layer (HTL). energetically aligned molecules reduced minority carrier recombination at NiOx/perovskite interface. As result, fully scalable 1.77 eV PSCs employing NiOx/2PACz hybrid HTL delivered champion power conversion efficiency 17.4%.

Abstract Perovskite‐organic tandem solar cells (TSCs) possess significant potential due to their unique features, such as orthogonal processing solvents, tunable bandgap, and infinite molecular designs. However, device performance is often hindered by the limited series current density, which constrained absorption of rear organic cell (OSC).

To mitigate charge collection issues arising from excessive thickness, contact passivation technique self‐assembled monolayer developed, minimizes non‐radiative recombination reduces Schottky barrier at interface, enabling more balanced hole‐electron transport.

However, despite ongoing progress perovskite‐silicon tandem cells, all‐perovskite (APTSCs) still lag counterparts. This raises question: can further development close this gap? Upon theoretical modeling combining optical electrical calculations, we found that: i) PCE limitations APTSCs are primarily caused by reflection losses at top perovskite interface; ii) introducing random texturing surfaces wide‐bandgap perovskites plays a critical role enhancing light absorption, which potentially improve up 30.97%. improvement be attributed reduced increased absorption both bottom narrow‐bandgap perovskites.
