Abstract

Perovskite solar cells (PSCs) rarely report, on a single-device platform, concurrent gains in optoelectronic efficiency and buried-interface mechanical robustness-two prerequisites for flexible and roll-to-roll (R2R) integration. We engineered a nanoplate-structured fluorine-doped tin oxide (NP-FTO) front electrode that couples light management with three-dimensional interfacial anchoring, and we quantified both photovoltaic (PV) and nanomechanical metrics on the same device stack. Relative to planar FTO, the NP-FTO PSCs achieved PCE of up to 25.65%, with simultaneous improvements in Voc (to 1.196 V), Jsc (up to 26.35 mA cm^-2), and FF (to 82.65%). Nanoindentation revealed a ~28% increase in reduced modulus and >70% higher hardness, accompanied by a ~32% reduction in maximum indentation depth, indicating enhanced load-bearing capacity consistent with the observed FF gains. The low-temperature, solution-compatible NP-FTO interface is amenable to R2R manufacturing and flexible substrates, offering a unified route to bridge high PCE with reinforced interfacial mechanics toward integration-ready perovskite modules.

纳米板结构FTO界面实现钙钛矿太阳能电池光电和机械性能的双重增强。

钙钛矿太阳能电池（PSCs）很少在单器件平台上同时获得光电效率和埋藏界面机械稳健性的收益，这是柔性和卷对卷（R2R）集成的两个先决条件。我们设计了一种纳米板结构的含氟氧化锡（NP-FTO）前电极，将光管理与三维界面锚定耦合在一起，并在同一器件堆栈上量化了光伏（PV）和纳米力学指标。与平面FTO相比，NP-FTO PSCs实现了高达25.65%的PCE，同时Voc（至1.196 V）， Jsc（高达26.35 mA cm-2）和FF（至82.65%）也有所改善。纳米压痕的降低模量增加了28%，硬度提高了70%，最大压痕深度减少了32%，表明承载能力的增强与观察到的FF增益一致。低温、溶液兼容的NP-FTO接口适用于R2R制造和柔性衬底，提供了一个统一的途径，将具有增强界面力学的高PCE连接到集成准备好的钙钛矿模块。

期刊介绍： Nanomaterials (ISSN 2076-4991) is an international and interdisciplinary scholarly open access journal. It publishes reviews, regular research papers, communications, and short notes that are relevant to any field of study that involves nanomaterials, with respect to their science and application. Thus, theoretical and experimental articles will be accepted, along with articles that deal with the synthesis and use of nanomaterials. Articles that synthesize information from multiple fields, and which place discoveries within a broader context, will be preferred. There is no restriction on the length of the papers. Our aim is to encourage scientists to publish their experimental and theoretical research in as much detail as possible. Full experimental or methodical details, or both, must be provided for research articles. Computed data or files regarding the full details of the experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material. Nanomaterials is dedicated to a high scientific standard. All manuscripts undergo a rigorous reviewing process and decisions are based on the recommendations of independent reviewers.
