Enhancing the performance of thin-film photovoltaic cells via the application of luminescent down-shifting layers. Photovoltaic (PV) devices convert sunlight directly into electricity. For decades, the dominant PV technology has been based on thick, costly silicon wafers. However, due to higher energy conversion efficiencies and manufacturing processes, thin film PV cells can provide lower price than of the conventional wafer-based technologies.

Photovoltaic (PV) devices convert sunlight directly into electricity. For decades, the dominant PV technology has been based on thick, costly silicon wafers. However, due to higher energy conversion efficiencies and manufacturing processes, thin film PV cells can provide lower price than of the conventional wafer-based technologies. This project takes one of the leading thin film technologies and couples it with a passive optical layer, which will result in a 30% performance enhancement by overcoming internal absorption losses. It is anticipated that the increased performance will enable the thin film PV technology to be far more commercially viable and attractive for future commercialisation, and hence reduce the cost of solar power.Read moreRead less

Short-pulse laser cleaning for Australian heritage conservation. Conserving heritage objects is a demanding discipline, requiring a suite of techniques for different problems. Overseas, laser cleaning using long pulse techniques leaves microscopic damage as discrete chunks of material are removed, and is unsuitable for many materials. We have developed a short pulse laser process which can remove material molecule-by-molecule in a controlled fashion, and which can be readily halted once the fi ....Short-pulse laser cleaning for Australian heritage conservation. Conserving heritage objects is a demanding discipline, requiring a suite of techniques for different problems. Overseas, laser cleaning using long pulse techniques leaves microscopic damage as discrete chunks of material are removed, and is unsuitable for many materials. We have developed a short pulse laser process which can remove material molecule-by-molecule in a controlled fashion, and which can be readily halted once the final finish is achieved. We will research this technique for application to unique Australian heritage materials that are important to the specific conservation needs of the Australian War Memorial, the RAAF, Navy and Army Museums, Artlab Australia, and the Art Gallery of NSW.Read moreRead less
