The square-ended prisms catch light at a range of different angles, channelling the energy to photovoltaic cells (which convert light to electricity) to generate four times more electricity than cells alone could produce.
Using a grid of concentrators and cells within a double-glazed window could have a significant impact on reducing energy consumption in the home, producing electricity that can be used throughout the building with the resulting environmental benefits.
GCU researchers, led by Dr Roberto Ramirez-Iniguez, have now patented the solar concentrator and the design algorithm for the production of new optical elements for building integrated photovoltaic systems.
Research has involved software simulation, 3D printing and moulds, leading to the production of commercially viable prototypes.
