Abstract:
1. A single optical device for a solar energy conversion system comprising: a first interface having a curved shape, the first interface being configured to disperse electromagnetic radiation based on wavelength and concentrate electromagnetic radiation; and a second interface having a curved shape, the second interface being configured to disperse electromagnetic radiation based on wavelength and concentrate electromagnetic radiation such that the focal areas of different wavelengths, relative to one another, are not parallel to the electromagnetic radiation that is incident upon the first interface, wherein the first interface and the second interface are configured to concentrate electromagnetic radiation of different wavelengths upon different target areas of a target device, wherein said target areas have different spectral sensitivity, and wherein said target areas are efficient in converting the electromagnetic radiation incident upon them into another form of energy, and wherein the second interface includes a plurality of draft surfaces having corresponding draft angles, the draft angles configured such that substantially no electromagnetic radiation having wavelengths corresponding to the wavelengths that are incident upon the target areas of the target device is incident upon the draft surfaces.
