Lead-free perovskite materials for solar cells and beyond (2025-2027)
Abstract
This project aims to develop new lead-free perovskite materials for next-generation solar cells and explore their application in new optoelectronics. To address the toxicity problem of lead containing perovskites, the key concepts are to design high-quality tin-based perovskite thin film devices through new interfacial engineering and defect passivation strategies. The expected outcomes include low-toxicity stable perovskite solar cells with record efficiencies, and new fundamental understanding of the material-property relationship. The project will significantly contribute to a decarbonised economy in Australia, and position the country at the forefront of renewable energy technologies and application of high-performance semiconductors.
