This project aims to develop a new defect-control approach for silicon-germanium heteroepitaxial semiconductor systems to provide a route for high-throughput, low-cost, high-efficiency silicon tandem solar cells. Mismatched heteroepitaxy of semiconductors is of considerable interest for fabricating novel devices. However, the use of highly-mismatched heteroepitaxial semiconductors has been limited due to the high densities of crystal defects which degrade the performance of both majority and minority carrier devices. This project aims to develop a new defect-control approach for heteroepitaxial semiconductors by continuous wavelength diode laser processing. With heteroepitaxial silicon-germanium as an example, the project will investigate the mechanism underlying defect-cleaning, optimised designs for best performance, and designs for high-efficiency tandem solar cells.Read moreRead less

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 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.Read moreRead less
