Devices and methods are described for more effectively collecting solar energy, including both visible and non-visible electromagnetic radiation to be converted into electrical energy. For example, a nanotube/nanowire device, comprising an electrical contact layer, semi-conductive layer, insulating layer, source electrode, drain electrode and semi-conducting nanotubes/nanowires can be used to collect solar energy from the UV to the infrared electromagnetic spectrum. Another example comprises a device that is capable of adjusting its frequency response to maximize power output according to the wavelength of electromagnetic radiation present. These devices and related methods are useful, for example, to provide an alternative electrical energy source, harness unused renewable energy, reduce carbon dioxide emissions, counteract global warming, and provide a carbon neutral energy source. The devices and methods are also useful, for example, to cool the interior of buildings, automobiles, airplanes, electronic devices/systems, etc. |
