This project aims to augment the overall electrical efficiency of concentrator photovoltaic solar systems that provide large-scale generation of cheap, clean electricity. Existing concentrator solar cells are highly efficient (>40%) but their performance is hampered by thick front-metal contacts that shade the cell. The project is expected to develop a new concentrator solar cell metalisation and insulation technology. The benefit of the project will be a direct increase in the system efficiency and simplified manufacturing of the concentrator solar receiver, which in turn reduces the cost of the concentrator power plant constructed by our Australian project partner RayGen Resources Pty Ltd.Read moreRead less

Summary
Two-Dimensional Material Tandem Detectors for Polarimetry and Spectroscopy. The aim of this project is to leverage the fundamental advantages that two-dimensional (2D) materials could provide to vertically-stacked (tandem) photodetectors. The strong absorption, tunable bandgap and polarisation dependence that many 2D materials exhibit, provides a means by which to detect properties of light. This topic is significant because it could overcome current cost/performance issues of tandem detectors, .... Two-Dimensional Material Tandem Detectors for Polarimetry and Spectroscopy. The aim of this project is to leverage the fundamental advantages that two-dimensional (2D) materials could provide to vertically-stacked (tandem) photodetectors. The strong absorption, tunable bandgap and polarisation dependence that many 2D materials exhibit, provides a means by which to detect properties of light. This topic is significant because it could overcome current cost/performance issues of tandem detectors, enabling widespread usage. The expected project outcome is the development of a novel tandem 2D detector, which as a single detector/pixel, can extract the intensity, polarisation and wavelength region of incoming light. This would provide benefits for many future applications, including machine vision and aerial surveying.Read moreRead less

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
