THERMAL REGULATING WAVELENGTH CONVERSION FILMS INCORPORATING PHASE CHANGE MATERIALS

This disclosure relates to a thermal regulating wavelength conversion film comprising a chromophore, an optically transparent polymer, and a phase change material. In some embodiments, the chromophore and phase change material are incorporated into the same polymer layer. In some embodiments, the chromophore and phase change material are incorporated into separate polymer layers. The thermal regulating wavelength conversion film is useful for converting incident wavelengths to more desirable wavelengths, while also absorbing and releasing heat to provide thermal regulation. The thermal regulating wavelength conversion film can be used as encapsulation for solar energy harvesting devices, a window film for building or vehicles, or may be used as a cover or roofing material for agriculture applications.
