Australian solar technology could significantly boost agricultural water-use efficiency, and help address future global food insecurity and water shortages.

Scientists from Edith Cowan University (ECU) have helped develop a world-first ‘Intelligent Glass’ solar technology for use in greenhouses.The technology converts the ultraviolet and infrared components of sunlight into electricity while allowing visible light – which is important for photosynthesis – to pass through the glass.

The glass structure is beileved to allow most of the visible light to pass through while more than 90% of the UV and 95% of IR radiation energy is scattered and partially routed to the edges of the glass, where it is collected by PV cells to produce electricity.The reduction in heating, cooling and lighting costs by using this solar glass is expected to achieve up to 40% energy savings in glass greenhouses.
