Atomic-scale structural characterisation of quantum-dot nanostructures for novel photovoltaic applications. This project aims to design, fabricate and characterise innovative quantum-dot solar cells in order to overcome the atomic-scale defects that limit current approaches. The scientific and engineering understanding acquired through this project will enable the rapidly growing global solar-cell industry to produce higher-efficiency III-V solar cells.
High quality copper-zinc-tin-sulphide absorber by one-stage reactive sputtering technology: a route to high efficiency/low cost thin film solar cells. International studies show that electricity from solar cells is one of the cleanest future energy sources, able to almost completely displace fossil fuels. This project, proposed to fulfil such a key role, targets greatly improved efficiency/cost ratio, by producing high quality CZTS thin film absorbers with a cost-effective fabrication technique.
Nanophotonics for strong absorption in extremely thin solar cells: moving beyond silicon. This project will lead to the development of extremely thin solar cells made of novel low-cost materials, which would likely reduce the cost of photovoltaic technology. If the cost of photovoltaics was sufficiently low then it could have a major impact on reducing greenhouse gas emissions and pollution in Australia and worldwide.

A new defect-control approach for mismatched heteroepitaxy semiconductors. 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.

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
Microscopy characterisation for the designing of Li-based batteries. This project aims to optimise the design of all-solid-state batteries by employing state-of-the-art microscopy and atomic tomography techniques. Demand for safer rechargeable batteries with higher energy densities has been rapidly increasing.

This project aims to optimise the design of all-solid-state batteries by employing state-of-the-art microscopy and atomic tomography techniques. Demand for safer rechargeable batteries with higher energy densities has been rapidly increasing. The safety issues associated with current lithium batteries become more serious with the size change (small for portable electronics and large for vehicles) because of the difficulty in handling of flammable organic liquid electrolytes. The scientific knowledge and engineering understanding acquired through this project will enable the battery industry to produce higher performance solid state batteries.Read moreRead less
Porphyrin arrays - Light Harvesting in three dimensions. The emulation of photosynthesis, the efficient and sustainable utilization of solar energy using renewable materials represents one of the great scientific challenges. This project will explore one aspect of this by determining the nature and scope of using assemblies of artificial chlorophylls for three dimensional light harvesting in titania solar cells.
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 ....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.Read moreRead less
Photochemical upconversion for third generation photovoltaic devices. Most solar cells cannot utilise infrared light, as the photons in this spectral region are not energetic enough to promote electrons across the energy threshold. This project will harvest this low energy light, and by 'gluing' the photons together in a process known as upconversion, the project will improve the light harvesting efficiencies of solar cells.
Kruppel-like factors and the methylome. This project aims to test the hypothesis that the KLF/SP family of transcription factors work in part via dynamic interactions with methylated cytosine nucleotides in DNA. This is fundamental to their function as pioneer factors in reprograming and their ability to co-ordinate differentiation and organogenesis. Conversely, dynamic changes in methylation status engage or disengage new regulatory elements in the genome via recruitment of KLF/SP family protei ....Kruppel-like factors and the methylome. This project aims to test the hypothesis that the KLF/SP family of transcription factors work in part via dynamic interactions with methylated cytosine nucleotides in DNA. This is fundamental to their function as pioneer factors in reprograming and their ability to co-ordinate differentiation and organogenesis. Conversely, dynamic changes in methylation status engage or disengage new regulatory elements in the genome via recruitment of KLF/SP family proteins as specific effectors. This project will address a new paradigm in genetics that is likely to underpin development.Read moreRead less
