Perovskite Solar Cells: From Lab to Real-World Application and Challenges
Metal halide perovskite photovoltaics have achieved power conversion efficiencies rivaling crystalline silicon, yet their transition from laboratory-scale devices to commercial deployment requires a paradigm shift toward application-specific engineering and macroscopic system integration. This review systematically evaluates the customized deployment of perovskite solar cells (PSCs) across diverse operational theaters, including building-integrated photovoltaics (BIPV), portable Internet of Things (IoT) systems, agricultural photovoltaics (Agri-PV), vehicle-integrated photovoltaics (VIPV), utility-scale tandems, and extreme space environments. Despite these opportunities, critical challenges persist in translating laboratory achievements into industrial-scale production. We critically evaluate primary bottlenecks hindering gigawatt-scale commercialization, focusing on the performance gap inherent in large-area manufacturing. Additionally, we analyze intrinsic material instabilities driven by dynamic ion migration and multi-scale lattice strain under realistic outdoor conditions. To conclude, we outline a strategic roadmap for overcoming these barriers, emphasizing lattice strain regulation, rigorous dynamic environmental testing protocols, and comprehensive sustainable lifecycle management. By synergizing mechanistic insights with scalable manufacturing and ecological assessments, this review provides a holistic framework to accelerate the ubiquitous commercialization of customizable, stable, and high-efficiency perovskite energy systems.
