Abstract
An energy-efficient transparent solar film is presented. The solar film has a first film layer with metal nanostructures. The metal nanostructures have plasmon resonances in wavelength bands greater than, or both less than and greater than visible wavelengths, depending on size and shape. The metal nanostructures have no plasmon resonance at visible wavelengths. In another aspect, metal oxide nanocrystals are formed with the first film layer. The metal oxide nanocrystals have absorption in a band of wavelengths less than visible wavelengths, and absorption in a band of wavelengths greater than visible wavelengths. Also provided is a solar film window and fabricating method.
