Abstract Halide perovskites hold great potential in developing next‐generation X‐ray detectors. However, preparing high‐quality and thick perovskite films a way compatible with thin‐film transistor (TFT)‐integrated flat‐panel detectors (XFPDs) remains challenging. Here, by engineering ink effective printability shape fidelity, direct writing (DIW) is developed as new approach to printing unique single‐crystal‐assembled (SCAP) film. In contrast polycrystalline grains consisting of randomly orientated crystal domains, the SCAP made tightly packed crystals well‐defined facets, showing 3–4 orders magnitude lower trap density (4.48 × 10 12 cm −3 ). Consequently, offers state‐of‐the‐art detection performance (sensitivity‐to‐dark current ratio: 1.26 11 µC Gy air −1 A ), low limit (114.2 nGy s negligible baseline drift (0.27 fA V Furthermore, XFPD based on 64 pixelated TFT array realizes high‐resolution digital radiography, opening avenue for further development

Abstract The formamidinium lead iodide (FAPbI 3 ) perovskite has emerged as a promising material for high‐efficiency photovoltaic applications. Although power conversion efficiency of more than 26% been achieved, stability issues have hindered its commercial application. In this study, the FAPbI under adverse conditions such humidity, oxygen, ultraviolet light, and temperature fluctuations is systematically reviewed. known effective strategies improving are discussed. Current studies shown that technologies doping, halide alloying, additive manufacturing engineering, interface modification identified in mitigating phase transitions enhancing environmental durability. Encapsulation technology further improves moisture heat resistance. Compared with other stabilization strategies, doping alloying can address effects narrowing absorption edge. Interface engineering an essential understanding mechanism, which will greatly improve problem practical application . This paper also looks forward to future research directions development trends.

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.

The photoelectric conversion efficiency (PCE) of perovskites remains beneath the Shockley-Queisser limit, despite its significant potential for solar cell applications. present focus is on investigating multicomponent perovskite candidates, particularly application machine learning to expedite band gap screening. To efficiently identify high-performance perovskites, we utilized a data set 1346 hybrid organic–inorganic and employed 11 models, including decision trees, convolutional neural networks (CNNs), graph (GNNs). Four descriptors were high-throughput screening: sine matrix, Ewald sum atom-centered symmetry functions (ACSF), many-body tensor representation (MBTR). results indicated that LightGBM CatBoost somewhat surpassed XGBoost in tree but random forests lagged. Among CNN models utilizing same four descriptors, CustomCNN VGG16 Xception, while EfficientNetV2B0 exhibited least favorable performance. When matrix served as adjacency matrices GNN GCSConv considerable improvement over GATConv slight advantage GCNConv. Significantly, outperformed other when with matrix. ideal combination algorithms identified was MBTR + CustomCNN, an R2 0.94. Subsequently, three exhibiting appropriate Heyd–Scuseria–Ernzerhof (HSE06) gaps define defects. them, CH3C(NH2)2SnI3 superior performance both vacancy substitutional defects compared C3H8NSnI3 (CH3)2NH2SnI3. This screening method establishes robust foundation selecting materials exceptional properties.

Narrow bandgap mixed tin-lead perovskite solar cells (PSCs) have garnered substantial research interest owing to their remarkable optoelectronic properties. However, non-radiative recombination and carrier transport losses at the interface between layer charge (C60) significantly reduce overall efficiency of PSCs. To address this challenge, 9-Fluorenylmethyl carbazate (9FC) is incorporated C60. The hydrazide group present in 9FC effectively mitigates oxidation Sn2+. Furthermore, can engage chemical bonding with perovskite, while outward-facing aromatic rings create effective π-π interactions C60, thereby promoting enhanced interfacial transfer. highest-performing PSCs achieve a power conversion (PCE) 23.97%, accompanied by an impressive open-circuit voltage 0.91 V. Additionally, these facilitate development highly efficient two-terminal four-terminal all-perovskite tandem cells, which demonstrate efficiencies 27.01% 28.07%, respectively.
