Abstract Flexible emerging photovoltaic technologies, such as organic and perovskite photovoltaics, hold great potential for integration into tents, wearable electronics, other portable applications. Recently, Fukuda et al. (2024) propose a bending test protocol standardizing the mechanical performance characterization of flexible solar cells, focusing on 1% strain over 1 000 cycles. This marked an important step toward establishing consistency good practices in literature. However, even with this unified protocol, accurately comparing flexibility cells is hindered by variated influence parameters like thickness, radius, power conversion efficiency ( PCE ) evolution during testing. Herein, new figure merit introduced, fatigue factor F ), which integrates retention, strain, cycles cohesive framework. Guided detailed multilayer model, metric enables more accurate analysis promotes consistent reporting, paving way optimization photovoltaics.

Interface stress is a critical challenge limiting the optoelectronic performance and stability of perovskite-based X-ray detectors, often causing severe issues such as surface roughness, cracking, film detachment during fabrication. To address this, polymer interlayers have been employed effective stress-buffering layers at substrate/perovskite interface. However, influence layer properties on growth quality perovskite films has received limited attention. In this study, we systematically explore processability, mechanical properties, solubility, thermal stability, adsorption strength with materials four polymers - poly(vinylidene fluoride) (PVDF), poly(vinylpyrrolidone) (PVP), polyimide (PI), poly(l-lactic acid) (PLLA) using combination experimental theoretical methods, emphasizing role molecular characteristics in enhancing CsPbI2Br quality. Among them, thick PI buffer demonstrates most uniform dense morphology, along strong adhesion to substrate, maintaining integrity even under 50 g load. The resulting detectors exhibit excellent uniformity long-term over 30 days continuous operation. Moreover, integration PI/CsPbI2Br 64 × thin-film transistor (TFT) enabled high-resolution imaging. This study provides valuable insights into selecting further optimize film-based detectors.

In detail, poly(acrylate ammonium) (PAAm), low-cost polymer with long chain structure, added into SnO2 aqueous solution reduce aggregation nanoparticles, resulting in deposition conformal high-quality film on tin-doped indium oxide surface. Simultaneously, PAAm addition can effectively regulate crystallization films, strengthening buried surface layer.

Abstract Pursuing high stability becomes the core challenge in realizing widespread application of perovskite solar cells (PerSCs). Here, a practical internal‐capsulation strategy is proposed by introducing cross‐linkable methacrylate analogs upon layer, hindering ion migration and preventing lead leakage to achieve stable PerSCs. Butyl (UMA) benzyl (BMA) can chemically interact with especially for BMA dimer significant π‐interactions among hanging benzene rings. Such configuration facilitated more compact coordination, thereby restoring Fermi level defect‐free state reducing carrier recombination losses. Moreover, integrating self‐cross‐linking intermolecular π‐effect, upgraded internal capsulation from linear protection mesh‐like scale. Consequently, not only boosted efficiency 25.31% but also greatly enhanced water resistance linkage. The upgrading marked an innovative direction protecting paving way sustainable PerSCs further application.
