Topic: Flexible Perovskite and Organic Optoelectronics for Wearable and Smart Systems

The rapid development of flexible and wearable technologies has accelerated the demand for innovative materials and device architectures. Perovskite and organic semiconductors have emerged as key enablers in this field, offering advantages such as mechanical flexibility, tunable electronic properties, and compatibility with various fabrication methods. This Special Issue focuses on recent breakthroughs in flexible optoelectronic devices, particularly light-emitting diodes, solar cells, energy harvesters, and sensors, based on perovskite and organic materials. These devices hold great promise for applications in wearable energy systems, flexible displays, and interactive electronics. We welcome research that explores both solution-based fabrication and vacuum deposition techniques, covering advances in materials, device architectures, and system-level integration. Contributions emphasizing scalable processes—such as printing and roll-to-roll manufacturing—as well as studies on mechanical durability and long-term operational stability are particularly encouraged. This Special Issue aims to provide a comprehensive overview of the current progress and future directions in flexible perovskite and organic optoelectronics for smart and wearable applications.
