Abstract:
1. A device for energy conversion, comprising: a device for adaptable wavelength conversion comprising at least one layer comprising a wavelength converting material and arranged to receive a first electromagnetic radiation, within and outside the visible spectrum, and re-emit a second electromagnetic radiation, wherein the device is arranged to manipulate the at least one layer to operate in a closed state, in which a surface of the at least one layer is substantially covered with the wavelength converting material and to operate in an open state, in which the surface of the at least one layer is substantially uncovered with the wavelength converting material; a solar cell configured to receive the second electromagnetic radiation; a control unit; and a spectrum detector, the spectrum detector configured to determine a frequency property of the first electromagnetic radiation and provide a signal including information about a specific spectrum of the first electromagnetic radiation to the control unit, and the control unit configured to control the device for adaptable wavelength conversion to switch between operating in the closed state and operating in the open state based on the signal.
