Organic, and more recently metal-halide perovskite semiconductors are redefining how functional electronic materials are processed for next-generation optoelectronic devices. Despite their distinct chemistries, these materials share common attributes, including exceptional optoelectronic performance, solution processability, and manufacturing paradigms that are intrinsically lower-cost and more versatile than incumbent inorganic semiconductors. Together, they offer transformative opportunities for sustainable energy technologies, advanced displays, wearable electronics, and emerging bioelectronic platforms. This symposium will connect diverse research communities to address common scientific and technological challenges that limit the translation of these materials from laboratory demonstrations to scalable, reliable technologies, providing a forum to discuss recent advances in materials design, manufacturing, and device processing across organic, perovskite, and hybrid organic inorganic semiconductor systems. Particular emphasis will be placed on the use of earth-abundant materials and low-toxicity solvent systems, directly addressing sustainability and environmental considerations that are increasingly central to emerging technologies. Contributions are welcomed that explore novel processing strategies enabling the transformation of advanced materials into device-relevant forms, alongside forward looking manufacturing concepts and lifecycle analyses of materials and devices. By positioning processing innovation as a unifying framework, this symposium aims to catalyse cross-disciplinary exchange and accelerate the development of sustainable, high-impact optoelectronic technologies
