All-perovskite tandem solar cells (TSCs) hold great promise in terms of ultrahigh efficiency, low manufacturing cost, and flexibility, stepping forward to the next-generation photovoltaics. However, their further development is hampered by relatively performance low-bandgap (LBG) tin (Sn)-lead (Pb) perovskite (PSCs). Improving carrier management, including suppressing trap-assisted non-radiative recombination promoting transfer, significance enhance Sn-Pb PSCs. Herein, a management strategy...
A self-assembled monolayer of DCB-BPA hole-selective layer facilitates the improved buried-interface quality, leading to a certified V OC 1.339 1.77 eV wide-bandgap perovskite solar cells.
All-perovskite tandem solar cells (TSCs) have exhibited higher efficiencies than single-junction perovskite (PSCs) but still suffer from the unsatisfactory performance of low-bandgap (LBG) tin-lead (Sn-Pb) subcells. The inherent properties PEDOT:PSS are crucial to high-performance Sn-Pb films and devices; however, underlying mechanism has not been fully explored revealed. Here, we report a facile oxalic acid treatment (OA-PEDOT:PSS) precisely regulate its work function surface morphology....
A DMPU custom-tailored solvent system effectively improved the film quality of perovskites, achieving one highest V OC 1.256 for 1.65 eV wide-bandgap PSCs.
Self-assembled monolayers (SAMs) have displayed unpredictable potential in efficient perovskite solar cells (PSCs). Yet most of SAMs are largely suitable for pure Pb-based devices, precisely developing promising hole-selective contacts (HSCs) Sn-based PSCs and exploring the underlying general mechanism fundamentally desired. Here, based on prototypical donor-acceptor SAM MPA-BT-BA (BT), oligoether side chains with different length (i.e., methoxy, 2-methoxyethoxy, 2-(2-methoxyethoxy)ethoxy...
Abstract Wide‐bandgap (WBG) perovskite solar cell (PSC) plays a pivotal role as the top subcell in all‐perovskite tandem cells (TSCs), facilitating absorption of high‐energy photons and affording large open‐circuit voltage ( V OC ). Nonetheless, stability efficiency WBG PSCs are constrained by light‐induced halide segregation non‐radiative recombination losses. In this study, work presents an approach utilizing 2‐methylpiperazinium bromide (2‐MePBr) via interfacial engineering to realize...
Abstract Tin (Sn)‐based perovskites as the most promising absorber materials for lead‐free perovskite solar cells (PSCs) have achieved record efficiency of over 14 %. Although suppressing oxidation Sn‐based is a frequently concerned topic PSCs, many studies given vague explanations and mechanisms are still under debate. This in principal due to lack an in‐depth understanding various complex intrinsic extrinsic factors causing process. In this context, we critically review chemical mechanism...
Abstract Tin (Sn)‐based perovskites have emerged as promising alternatives to lead (Pb)‐based in thin‐film photovoltaics due their comparable properties and reduced toxicity. Strains can be tailored modulate optoelectronic properties, but mechanisms for the effects of strains on Sn‐based perovskite films devices are unrevealed corresponding strain engineering is unexplored. Herein, a strategy developed through incorporating 4‐fluorobenzylammonium halide salts (FBZAX, X = I, Br, Cl) into...

Abstract Wide‐bandgap (WBG) perovskite solar cells (PSCs, E g > 1.6 eV), serving as the top cell in perovskite/silicon tandem (PSTSCs), play an indispensable role absorbing high energy photons and increasing overall efficiency. However, WBG PSCs often suffer from severe light‐induced phase segregation significant non‐radiative recombination losses due to uncontrolled rapid crystallization. Here, polyfluoride molecular additives are designed incorporated via (diacetoxyiodo)benzene into...
Low-bandgap (LBG) tin-lead (Sn-Pb) perovskites are essential for tandem solar cells but face challenges because the use of a hygroscopic PEDOT:PSS hole transport layer (HTL) reduces device stability. A HTL-free structure can overcome these issues introduces new drawbacks like imbalanced carrier and severe recombination. This study 3-amino-5-mercapto-1,2,4-triazole (AMTZ) as rear interface passivator to simultaneously mitigate defects stabilize Sn-Pb perovskite films. The aromatic triazole...
Abstract The regulation of buried interface is crucial for high‐performance wide‐bandgap perovskite solar cells (PSCs), which can influence the interfacial defects, charge transport, and crystallization perovskites. In this work, a facile strategy reported inserting multi‐functional (Z)‐4‐Fluoro‐ N ′‐hydroxybenzimidamide (4F‐HBM) molecule between self‐assembled monolayer (SAM) (WBG) layer, actively regulating crystal growth promoting hole extraction. It found that F atoms in 4F‐HBM form...
Abstract Tin (Sn)‐based perovskite solar cells (PSCs) are extremely vulnerable to oxygen. Nevertheless, mechanism understanding and fundamental strategies achieve oxygen‐stable Sn‐based PSCs lacking. Here a nucleation‐layer assisted (NLA) strategy by forming nucleation layer at the interface of hole transport attain highly quasi‐2D Ruddlesden‐Popper (RP) is reported. The formation process consists washing off prepared film annealing residue on substrate, which produces new substrate for...
