In situ electron microscopy toward new materials and applications. This project aims to develop materials for structural and green energy applications, using spatially-resolved, dynamic in situ transmission electron microscopy to research fundamental mechanical, electrical, thermal, optical, optoelectronic and photovoltaic properties of diverse nanostructures. These techniques measure nanomaterial (one-dimensional nanotubes and nanowires and two-dimensional graphene-like nanosheets) response to external stimuli, including mechanical, electrical, optical and thermal stimuli. Anticipated outcomes are new ultralight and superstrong structural composites and ‘green-energy’ nanomaterials, such as solar cells, touch panels, batteries, supercapacitors, field-effect transistors, light sensors and displays.Read moreRead less
Indoor Photovoltaics Enabled by Wide-Bandgap Perovskite Quantum Dots. This project aims to develop a high-efficiency indoor photovoltaic (PV) technology to provide reliable low-cost power in the multi-billion dollar “Internet of Things” (IoT) market. There are currently no devices that meet the requirements for maximum operating efficiency under indoor illumination.

This project aims to develop a high-efficiency indoor photovoltaic (PV) technology to provide reliable low-cost power in the multi-billion dollar “Internet of Things” (IoT) market. There are currently no devices that meet the requirements for maximum operating efficiency under indoor illumination. We propose to solve this problem by fabricating PV cells using colloidal perovskite quantum dots that offer class-leading stability and band gap tunability across the required range, enabled by quantum confinement. The outcome is the development of integrated self-powered IoT devices potentially impacting Advanced Manufacturing growth in Energy, Cyber Security, Food and Agribusiness, as all of these will ultimately rely on networked smart devices.Read moreRead less
Nano-fibrous structure for high-performance organic photovoltaic thin films. This project aims to create nano-fibrous active thin films with high charge mobility for organic photovoltaic (OPV) devices, using a method inspired by molecular gelation. The significance of this project is that it addresses a major bottleneck, i.e. poor charge generation and transport, that limits the efficiency of OPV devices.

This project aims to create nano-fibrous active thin films with high charge mobility for organic photovoltaic (OPV) devices, using a method inspired by molecular gelation. The significance of this project is that it addresses a major bottleneck, i.e. poor charge generation and transport, that limits the efficiency of OPV devices. The outcomes will provide insights into the crucial factors that affect the self-assembly of organic semiconducting materials, and the influences of nano-fibrous structure on the charge mobility and efficiency of an OPV device. The outcomes will greatly facilitate the development of highly efficient, lightweight and low-cost solar energy harvesting devices to reduce our carbon footprint.Read moreRead less

Breaking Performance Limits of Solar Inverters for a Sustainable Future. Micro-inverters offer a unique ability to maximise solar energy yield and streamline the installation, operation and maintenance process of solar power generation, thus having huge potentials to drastically reduce the cost of solar electricity.

Micro-inverters offer a unique ability to maximise solar energy yield and streamline the installation, operation and maintenance process of solar power generation, thus having huge potentials to drastically reduce the cost of solar electricity. However, performance limits have hampered their wider applications in the energy sector. This project aims to tackle the performance challenges of micro-inverters by developing a novel power-conversion architecture, a unified design framework, and a new control theory. The intended research outcome will be a new range of ultra-high-performance micro-inverters. This will promote greater solar uptake and maintain Australia’s leadership in the development of disruptive solar power generation technology.Read moreRead less

This project aims to develop a detailed understanding of the drivers behind the recent rapid rise of photovoltaic (solar) energy products in East Africa through extensive fieldwork research in Kenya and Uganda. This project expects to generate new knowledge on the complex dynamics of renewable energy transitions in Africa. Expected outcomes of this project include the development of theoretical, empirical and policy insights that will inform how sustainable and just energy transitions are able to be realised in energy poverty contexts in the Global South. This should provide benefits, such as helping to inform the actions of governments, aid donors, businesses and organisation working to eliminate energy poverty in Africa.Read moreRead less
