Abstract engineering has emerged as a promising approach to improve the stability and power conversion efficiency of perovskite solar cells (PSCs) by regulating crystallization or defects. Conventional methods typically focus on single functional group, leading deficiency in simultaneously addressing above mentioned two aspects. Here, an innovative using (methylsulfonyl)phenyl)prop‐2‐en‐1‐amine hydroiodide (MSPPAI) is presented concurrently effectively modulate defect passivation. The unique structure MSPPAI, combining rigid conjugated with multisite anchoring groups (─NH 2 ─SO ─), enables precise regulation through strong interaction components. This promotes preferred (100) orientation crystals, enhances grain size, thus improves film quality. Meanwhile, approximate coplanarity further facilitate ordered directional growth. Furthermore, preventing volatile loss coordinating residual Pb 2+ , MSPPAI could stabilize boundaries surfaces reduce defects prevent degradation. Utilizing these mechanisms, corresponding based devices achieves 25.54% exhibits excellent that maintains 93% its initial even after 1600 h under humid conditions. molecular design strategy presents novel for improving PSCs.

This study presents a novel investigation into enhancing the environmental stability of perovskite thin films, specifically focusing on effects AZ5214 photoresist compared to widely studied PMMA. By employing advanced matrix encapsulation techniques, we aim stabilize methylammonium lead iodide (MAPbI 3 ) and bromide (MAPbBr which are meticulously prepared via two-step solution deposition method under controlled ambient conditions. Our approach involves spin-coating layers poly(methyl methacrylate) (PMMA) singularly encapsulate films. provides robust hydrophobic barrier, significantly mitigating moisture ingress addressing pinhole challenges within structure. Through comprehensive characterizations—including scanning electron microscopy (SEM), X-ray diffraction (XRD), photoluminescence (PL) spectroscopy—we demonstrate that photoresist, despite being thicker than PMMA, offers enhanced stability. revealed coating MAPbI with 127-nanometer layer PMMA resulted in PL intensity retention 44.8% after 40 days, is 589.23% improvement over uncoated perovskite. Similarly, 1200-nanometer achieved 38.2%, reflecting 487.69% enhancement. For MAPbBr perovskite, 43.1%, 71.72% improvement, while 48.4%, showing 92.83% These findings highlight superior provided by especially for , making it more effective barrier against degradation

Perovskite solar cells (PSCs) have attracted widespread attention due to their low cost and high efficiency. So far, a variety of single‐junction PSCs been successfully developed considered for commercialization, including normal (N‐PSCs), inverted (I‐PSCs), carbon‐based (C‐PSCs) without hole transporter. Herein, the material cost, equipment depreciation energy consumption these three types (1 m 2 ) in detail are analyzed. As indicated, total fabrication N‐PSCs ($86.49) I‐PSCs ($81.31) is very close, but significantly reduced $41.16 C‐PSCs (49%–52% reduction) because carbon electrode much cheaper than noble metal organic Besides, only low‐cost slot‐die coating process with needed deposition electrode, while expensive physical vapor reactive plasma processes

Abstract Dipole molecules (DMs) show great potential in defect passivation for printable mesoscopic perovskite solar cells (p‐MPSCs), although the crystallization process of p‐MPSCs is more intricate and challenging than planar cells. In this work, a series non‐volatile multifunctional DMs are employed as additives to enhance perovskites improve both power conversion efficiency (PCE) stability devices. This enhancement achieved by regulating side groups benzoic acid with electron‐donating such guanidine (─NH─C(═NH)─NH 2 ), amino (─NH ) formamidine (─C(═NH)─NH ). form hydrogen bond interactions organic cations establish electrostatic PbI 6 4− . The synergistic effect these suppresses formation, enhances film crystalline quality, reduces crystal density, mitigates non‐radiative recombination, effectively carrier transfer extraction efficiency. Furthermore, incorporation leads reconstruction surface energy level, thereby enhancing hole at perovskite/carbon electrode interface. optimized achieve PCE 19.23%. unencapsulated device demonstrates promising long‐term storage stability, retaining 91% original after 1440 h aging 40 ± 5% relative humidity 30 5 °C.
