| Abstract | We propose to develop a novel type of solar cell that will generate electricity from sunlight with efficiency above 30 . This is at least twice the efficiency of the cells currently used to power roadside signs and comparable with the highest efficiency tandem cells which power satellites in space. However, our cell offers many advantages over the tandem, in particular the absence of a tunnel-junction. This means they can cope with the large variations in the intensity and spectral contentof sunlight on buildings and in the light-concentrating systems which reduce the cost of solar electricity. Our cell is particularly suited to an exciting new application - smart windows. These are double-glazed facades containing arrays of small plastic lenses which follow the sun s movement and focus sunlight onto small, unobtrusive solar cells. Direct sunlight is removed and the air-conditioning load reduced, while the smart windows provide combined heat and power (CHP) for the building. Even inLondon the electricity generated would power the office behind a south facing wall. The smart windows also allow glare-free diffuse sunlight into the room, which is ideal lighting for a computer screen. The cells will also be ideal for integration into hybrid CHP systems that provide electricity and hot water from concentrated sunlight with a natural gas backup. The new device incorporates the novel, nanostructured solar cell that the Imperial group have developed in collaboration with the EPSRCNational Centre for III-V Technologies. The Centre for Sustainable Technologies will characterise the cell performance on prototype concentrators of the new UK company SolarStructure, which has recently been formed to manufacture smart windows | |
