Australian researchers develop vapour-based manufacturing process for lead-free perovskite solar
University of Queensland researchers have developed a scalable, lead-free perovskite solar cell manufacturing process that achieves record indoor-light efficiency without toxic materials. The new method eliminates the need for hazardous solvents and lead, making it better suited for scalable manufacturing. The panels made using this process are thin, scalable, and can be integrated into a range of products, offering an alternative to batteries for low-power electronics. The technology has the potential to replace silicon with higher efficiencies and commercial potential, with applications in consumer electronics and environmental sensors. Further testing is needed to ensure protection from oxygen and moisture.
