Scalable, Stable and Sustainable Perovskite Solar Cells: From Engineering to Outdoor Reliability

Metal–halide perovskite solar cells are redefining photovoltaic research through their exceptional light absorption, tunable bandgap, long carrier diffusion lengths, and compatibility with tandem architectures. In less than a decade, power conversion efficiencies have soared to rival those of crystalline silicon, opening pathways to low-cost and high-performance solar energy technologies. Yet, despite this remarkable progress, perovskite absorbers and interfaces remain highly sensitive to environmental and operational stressors such as moisture, oxygen, heat, illumination, and electrical bias. Most record-performing devices are developed on small areas under controlled laboratory conditions, creating a persistent gap between laboratory performance and scalable manufacturing. To enable real-world deployment, the community is shifting toward a deeper understanding of degradation mechanisms, more robust device interfaces, scalable processing, and validation of module stability under realistic outdoor operating conditions.This Research Topic aims to advance the scientific and engineering foundations required for the commercialization of metal-halide perovskite solar cells. Unlike other thin-film technologies, perovskite photovoltaics face unique physicochemical challenges, including ion migration, hysteresis, interfacial degradation under bias and illumination, and limited reproducibility during large-area deposition. By gathering research across chemistry, materials science, device physics, and reliability engineering, this collection will highlight innovations that bridge the gap between high-efficiency laboratory prototypes and durable, industrially compatible modules. Key goals include understanding mechanisms of instability, developing sustainable device architectures, and optimizing interfaces, encapsulation, and processing routes for long-term operation.• Composition and defect engineering of metal–halide perovskite absorbers• Interface and contact engineering, including self-assembled monolayers and transport layers• Ion migration, hysteresis, and charge recombination in operating devices• Advanced characterization techniques (impedance spectroscopy, IMPS/IMVS, photoluminescence, electroluminescence, transient analyses, conducting atomic force and Kelvin probe force microscopy etc.)• Encapsulation and barrier design for moisture and thermal protection• Scalable fabrication (blade coating, slot-die coating, screen printing, inkjet printing, gravure printing, evaporation, hybrid processes)• Flexible and tandem devices (perovskite/silicon, perovskite/organic, and all-perovskite tandems)• Module-level validation, outdoor testing, and long-term reliability assessment (e.g., ISOS stability protocols)• Life-cycle analysis and techno-economic evaluation of perovskite photovoltaics Topic editors: Apostolos Ioakeimidis, Chandra Shakher Pathak, Ananthanarayanan Krishnamoorthy, Ershad Parvazian, Damian Glowienka Source: https://www.frontiersin.org/research-topics/84177/scalable-stable-and-sustainable-perovskite-solar-cells-from-engineering-to-outdoor-reliability
