A device for adaptable wavelength conversion and a device for energy conversion are described. The device for adaptable wavelength conversion comprises at least one layer comprising a wavelength converting material and arranged to receive and re-emit a light beam. The device is further 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. The device for adaptable wavelength conversion can be applied in combination with a solar cell or photovoltaic cell thereby enabling the solar cell to receive radiation having a suitable spectrum under varying lighting conditions.
