A compact portable solar powered energy concentrator

University of New South Wales, Australia

In order to use solar energy to either produce high temperatures for increased chemical reaction kinetics for example, or high radiant energy flux for surface interactions, it is necessary to focus the incoming sunlight to increase the local radiation flux.

What is the technology?
The invention uses micro and nano-fabrication techniques to produce an array of micro-lenses to focus light onto an array of micro-channels tens of micrometers wide. The micro-channels contain specific components, such as thin film selective surfaces, photovoltaic cells or titanium dioxide photo-catalysts.
