Claim 14:
15. A method for cooling an area of a motor vehicle, comprising:
coupling in incident radiation as coupled-in incident radiation, by a diffractive optical element disposed on a surface of the motor vehicle, the diffractive optical element configured to,
be transparent to at least a first part of a visible wavelength range of incident radiation in a section on the surface of the motor vehicle to induce light,
couple in the incident radiation, and
conduct at least a second part of a wavelength range of the coupled-in incident radiation away from an area of the motor vehicle to be cooled;

conducting the coupled-in incident radiation away from the area of the motor vehicle to be cooled;
conducting the coupled-in incident radiation from the diffractive optical element to an absorber of a radiator of the motor vehicle;
converting, by a thermoelectric generator included in the radiator, at least part of the coupled-in incident radiation into electrical energy; and
releasing the electrical energy, by the radiator.
