Over the past decade, metal halide perovskites have revolutionized the fields of photovoltaics and optoelectronics, achieving record-breaking efficiencies through rapid innovations in materials and interfaces. However, as the field approaches technological maturity, the critical challenges now lie in long-term operational stability, environmental resilience, and industrial scalability. This symposium will address these next-generation frontiers, focusing on strategies that translate laboratory breakthroughs into viable, durable, and sustainable technologies. We invite contributions that explore the physical, chemical, and engineering aspects of stability in perovskite solar cells and optoelectronic devices. Topics include degradation mechanisms, defect passivation, interface and encapsulation engineering, and the design of environmentally benign and lead-free compositions. Discussions will also highlight scalable deposition techniques, tandem integration with silicon and other semiconductors, and system-level approaches that ensure reproducibility and manufacturing compatibility. Beyond materials optimization, the symposium aims to foster dialogue on circular-economy principles, green fabrication processes, and lifecycle analysis for perovskite-based technologies. Interdisciplinary perspectives, ranging from materials chemistry to device physics and reliability engineering, are strongly encouraged. this symposium aims to establish a roadmap for the real-world deployment of perovskite optoelectronics, ensuring that future devices are not only efficient but also stable, scalable, and sustainable.
