The system will have a low profile and will be nearly invisible from the street. The system will track the sun. Concentration will be accomplished by a mixture of refraction and reflection. About 20% of the sunlight will be converted to electricity using lines of tiny solar cells, with the balance being converted to heat which is removed by cooling fluid and stored in hot water tanks.Read moreRead less

The development of low-cost photovoltaic concentrator systems will allow the large scale depoyment of these systems, both in Australia and overseas. The current size of this market is several hundred MW of electricity per year, and growing rapidly. This will have both environmental benefits (though reduced greenhouse gas emissions)as well as economic and social benefits - through the creation of empoyment opportunities in PV manufacturing and the generation of export earnings. It could be of particular benefit to remote communities requiring reliable, low cost off-grid power generation.Read moreRead less
Increase in Photocatalytic Activity of TiO2 through Intervalence Charge Transfer. Titanium dioxide (TiO2) has many proposed and realised applications in energy and the environment. The main problem that has hindered development and commercialisation of devices using TiO2 is its low photocatalytic activity, which results from its poor absorption of visible and infrared light. Most researchers modify the properties of TiO2 by conventional electrochemical methods to improve its performance but the ....Increase in Photocatalytic Activity of TiO2 through Intervalence Charge Transfer. Titanium dioxide (TiO2) has many proposed and realised applications in energy and the environment. The main problem that has hindered development and commercialisation of devices using TiO2 is its low photocatalytic activity, which results from its poor absorption of visible and infrared light. Most researchers modify the properties of TiO2 by conventional electrochemical methods to improve its performance but these attempts have been of limited success. The present research involves a completely new approach to the problem, which is based on the method used in the heat treatment of sapphire to improve its colour. This approach uses a phenomenon involving the modification of the optical properties to improve its absorption of light.Read moreRead less

This project aims is to develop fully hermetic, vacuum encapsulation for perovskite solar cells as energy harvesting glazing systems in buildings with high thermal insulation. This glazing system should simultaneously mitigate heat gain in summer and heat loss in winter, control the entry of light, and generate electric power. This project seeks to develop a new advanced glass encapsulation method with electrical feedthroughs that is fully compatible with perovskite solar cells. It should revolutionise the architectural glazing market with a new generation product with unprecedented electrical power generation capacity and a simultaneous increase in thermal insulation to provide the ultimate energy solution for future cities. An expected outcome from this project is a range of new products to expand the solar market beyond roof-top applications and solar farms.Read moreRead less
