Tin perovskites present promising alternatives to lead perovskites, offering comparable optoelectronic properties alongside environmentally friendly characteristics. However, the rapid crystallization and easy oxidation of Sn2+ poor film quality, further constraining device performance. Here, 4-hydroxypyridine (4-HP) is introduced into tin perovskite precursor for fabrication high-quality films. 4-HP could modulate colloidal size prenucleation clusters in precursor, thus inducing fast nucleation retarding crystal growth rate through formation chemical interaction between nitrogen pyridine ions. Furthermore, hydroxyl group on ring contributes suppressing Sn2+. As a result, power conversion efficiency (PCE) devices based increases up 11.3%. The stability unencapsulated shows significant improvement, retaining 100% their initial PCEs after 2000 h storage N2 with 50–100 ppm O2. This research presents novel approach synchronized regulation suppression oxidation.

Meeting future energy demands with sustainable sources like photovoltaics (PV) presents significant land and logistical challenges, which can be mitigated by improving PV power conversion efficiency (PCE) decentralized solutions building-integrated solar-integrated mobility systems (e.g., Unmanned Aerial Vehicles (UAVs)). Metal Halide Perovskites Solar Cells (MH-PSCs) provide a transformative, low-cost solution for high-efficiency diverse compositions, exceptional optoelectronic properties, low-temperature, solution-based processability. Conventionally the MH-PSCs are fabricated in "p-i-n" or "n-i-p" configuration on glass-Transparent Conductive Oxide (TCO) substrates. While glass-based Perovskite (PSCs) have achieved remarkable efficiencies, their limited scalability, high areal-weight, mechanical rigidity greatly limit usage wearables electronics, BIPVs, e-mobility applications. Addressing these challenges requires "targeted architectural innovations" MH-PSCs, tailored to specific applications, drive practical deployment forward. This study reviews four innovative PSC architectures-Interdigitated Back Contact (IBC) PSCs, Lateral Configuration (LC) Fiber-Shaped (FS) Substrate-Configuration (SC) PSCs-highlighting design advancements enhanced efficiency, flexibility, lightweight, application-specific integration. Importantly, review discusses precise engineering required each layer of innovations ensure compatibility, efficient charge transport, durability, scalability while optimizing performance, also identifying key outlining directions R&D.

Abstract Various popular large organic cations have been extensively used as the essential additives in perovskite precursor solution due to their satisfactory passivation effect but may produce low‐n value (n ≤ 2) 2D phases with undesired distribution. Meanwhile, remaining easy oxidation of Sn 2+ and p‐type self‐doping perovskites are also detrimental ultimate photovoltaic properties stability tin (Sn)‐based solar cells (PSCs). Here, 3AMPYSnI 4 crystals (3AMPY = 3‐(aminomethyl)pyridinium)) designed applied adjust crystallization process phase distribution Sn‐based perovskite. Consequently, strong coordination interaction between 3AMPY 3D components introduced nucleation sites by not only decreases increases phase, inhibits self‐p‐doping perovskites, resulting lower trap density non‐radiative recombination loss, faster carrier extraction transfer, higher for 2D‐3D PSCs. As a result, optimized devices deliver an increased power conversion efficiency from initial 10.91% 13.28% retain 96.0% original performance more than 3000 h nitrogen (N 2 ) atmosphere.

Recent advances in tin-based perovskite solar cells (TPSCs) have yielded significant gains power conversion efficiency (PCE), yet progress on wide-bandgap (WBG) tin perovskites remains limited, primarily due to the complexities of halogen composition tuning and associated phase segregation. Here, a composition-independent strategy is presented for realizing WBG TPSCs by partially substituting formamidinium with dimethylammonium (DMA) A-site lattice. This substitution expands lattice, widening bandgap from 1.63 1.72 eV without requiring additional bromine. Comprehensive structural optical analyses reveal enhanced crystallinity, reduced strain, improved film morphology. Furthermore, ultraviolet photoelectron spectroscopy confirms band alignment hole transport layer, enabling more efficient charge extraction. By employing dielectric/metal/dielectric transparent electrode, semi-transparent (ST-TPSCs) are fabricated PCE 10.37% high near-infrared transmittance, which well-suited tandem applications. Stacking this ST-TPSC narrow-bandgap TPSC yields first four-terminal, lead-free device, achieving combined 15.02%. These findings show that DMA incorporation effectively addresses challenges relying adjustments, providing robust pathway toward high-efficiency, eco-friendly photovoltaics highlighting promise next-generation cells.
