Stable Non-toxic Organic-inorganic Halide Perovskite Solar Cells

The project aims to develop next-generation organic-inorganic halide solar cells which are stable and non-toxic. Although rapid progress has been made in the emerging perovskite solar cell technology, it currently relies on lead as a key perovskite component. The elimination of lead from organic-inorganic halide perovskite solar cells would greatly increase their acceptance as an alternative thin film photovoltaic solution because of their low cost and non-toxic nature. The dearth of lead-free perovskite solar cell demonstrations and the relatively low conversion efficiencies demonstrated understate their potential. This project plans to improve understanding of their photovoltaic enabling attributes by characterising and modelling their optical and electrical properties. It then plans to apply new fabrication methods to develop lead-free solar devices.
