Summary
Combined reactor for the plasma-enhanced chemical vapour deposition (PECVD) of amorphous layers of silicon, silicon nitride and silicon oxide, and for Reactive Ion Etching. Our small, but very productive group (up to 30 publications per Discovery grant) has reached critical mass (8 people), and the acquisition of essential infrastructure is peremptory. Without the proposed plasma reactor our strong international impact (10 papers, one invited, at the 2003 world conference on photovoltaics) will ....Combined reactor for the plasma-enhanced chemical vapour deposition (PECVD) of amorphous layers of silicon, silicon nitride and silicon oxide, and for Reactive Ion Etching. Our small, but very productive group (up to 30 publications per Discovery grant) has reached critical mass (8 people), and the acquisition of essential infrastructure is peremptory. Without the proposed plasma reactor our strong international impact (10 papers, one invited, at the 2003 world conference on photovoltaics) will wane. This machine permits to deposit thin layers of silicon nitride and amorphous silicon and is a versatile tool for investigating silicon materials for photovoltaics and microelectronics. Such reactors have become an essential tool for silicon solar cell work. Most laboratories across the world have at least one, including UNSW, but access to the latter is impractical.Read moreRead less

The project aims to increase the amount of available energy intake from photovoltaic panels, lengthen lifetime of power DC/AC inverter, reduce the amount of energy waste due to inefficient inverter by introducing new switching power converters with direct power transfer technique - bypassing part of the input power without repeatedly processing it, and using long-life ceramic type capacitors. Development of this technology will mean reduced total cost, improved product lifetime and reduced global warming. It will lead to a reliable product that will help to put the Australian switching power converter industry into a leading position internationally in the design and manufacture of DC/AC inverters.Read moreRead less

The project aims to reduce the amount of energy waste and cost due to inefficient AC/DC power supplies by introducing a novel power supply technique - combining conventional two-stage power circuits and using time-multiplexing control. Improvements in power supply efficiency and size will mean reduced total cost, improved product lifetime and reduced heating up of the environment, leading to a reliable product that is particularly relevant to the Australian switching power supply industry. The development of this technology will help to put Australia into a leading position internationally in the design and manufacturing of AC/DC power supply.Read moreRead less
Nanostructured Silicon-Based Tandem Solar Cells. The expected outcome from the project is a new generation of low-cost silicon solar cell that will significantly reduce the costs of generating electricity from sunlight. Solar cells are presently the world's most rapidly growing energy source, with Australians and Australian companies already major players in the associated rapidly expanding industry. Solar cells represent the most benign technology yet suggested for supplying the world's future ....Nanostructured Silicon-Based Tandem Solar Cells.

Solar cells are presently the world's most rapidly growing energy source, with Australians and Australian companies already major players in the associated rapidly expanding industry. Solar cells represent the most benign technology yet suggested for supplying the world's future energy needs. A cleaner environment in the future than would otherwise be likely is another expected outcome as is the creation of major new opportunities for Australian industry.Read moreRead less

Improving silicon grain boundaries by linking electronic material quality and device manufacturing conditions. This project develops our recent findings for improving silicon grain boundaries in electronic devices such as cheap solar cells, active matrix displays, thin-film transistors, etc. The performance of such devices and their applications have been limited mainly because no simple link between manufacturing conditions and device quality has been found. However, we recently verified a phys ....Improving silicon grain boundaries by linking electronic material quality and device manufacturing conditions. This project develops our recent findings for improving silicon grain boundaries in electronic devices such as cheap solar cells, active matrix displays, thin-film transistors, etc. The performance of such devices and their applications have been limited mainly because no simple link between manufacturing conditions and device quality has been found. However, we recently verified a physical model description of grain boundaries on a broad range of devices, and this allows us to find such a link and to address prevailing problems from a new perspective. This will improve both the understanding and the manufacturing of such devices.Read moreRead less
Innovative Grid-Connected, Small-Scale Wind Turbine Generators Offering Low Cost and Wide Operating Speed Range. Growing concerns about sustainability issues with fossil fuels have resulted in strong interest in wind power worldwide.

Growing concerns about sustainability issues with fossil fuels have resulted in strong interest in wind power worldwide. Grid-connected inverters are an efficient way of utilising small wind turbines on domestic, farming or small commercial properties which have access to the power grid. Existing small-scale, grid-connected wind turbines are expensive and have a limited operating wind speed range. We are investigating new designs for low-cost wind turbine generators which can produce power over a wide range of wind speeds. The project should result in a greater application of small-scale wind generators in Australia and will lead to reductions in fossil fuel usage and greenhouse gas emissions.Read moreRead less
Novel Partial Discharge Detection Technique based on an Overhead Transmission Line Sensing Architecture. Overhead power transmission systems are a common instigator of fires through the production of sparks from faulty insulators. Australia is experiencing extended hot and dry conditions that amplify the risk of these events becoming large scale bushfires, causing millions of dollars of damage and destroying immeasurable amounts of native flora and fauna. The overhead transmission line sensing ....Novel Partial Discharge Detection Technique based on an Overhead Transmission Line Sensing Architecture. Overhead power transmission systems are a common instigator of fires through the production of sparks from faulty insulators. Australia is experiencing extended hot and dry conditions that amplify the risk of these events becoming large scale bushfires, causing millions of dollars of damage and destroying immeasurable amounts of native flora and fauna. The overhead transmission line sensing system proposed in this research will provide power companies with a cost effective insulator condition monitoring tool to continually survey Australia's aging electrical infrastructure. This ensures a reliable electricity supply to consumers, while also protecting the ecosystems of Australia's bushland. Read moreRead less

The Fellowship would be used to launch a major new initiative addressing one of the key challenges facing microelectronics, the incorporation of optical functions into high density silicon integrated circuits, as well as accelerating development of a "third" generation of photovoltaic solar cells using similar techniques. This third generation thin-film technology would be capable of fundamentally higher energy conversion efficiency than earlier generations, at low cost. In both cases, the targeted outcome over the period of the Fellowship is to develop technology to the stage where it can be commercially evaluated, in a way likely to maximise Australian benefits.Read moreRead less

The project aims to investigate methods for extracting and converting intermittent energy from variable speed wind generators and supplying to electricity grids. Low cost power conditioning units for integrating small-scale wind generators will be designed, developed and commercialised. It is expected that this project will lead to a systematic design procedure for grid connected inverter technology using a novel current control technique, and extraction of more energy from small scale wind turbines especially at low wind speeds. Successful commercialisation will result in significant reduction in cost resulting wider application of wind turbines, substantial economic benefit to the commercial partners as well as Australian communities in rural areas.Read moreRead less
