Abstract

See full text

In a method for manufacturing of thermochromic material, a target increased luminous transmittance level for the thermochromic material is determined (210). The luminous transmittance level is defined within a predetermined wavelength region. Preferably, this predetermined wavelength region at least partly comprises visible light. A concentration level of a first dopant element is determined (212) for generating the luminous transmittance level of the thermochromic material. The first dopant element is capable of forming an oxide having a high bandgap in its electronic structure, and in a specific embodiment is Al and/or Mg. A VO2-based thermochromic material is doped (214) with the determined concentration level of the first dopant element. At least one second dopant may also be employed.
