Abstract: Spectrally selective coatings have potentially important applications in solar/thermal/electric conversion, solar heating, and window insulation. These coatings can be divided into two classes: transparent heat mirrors and selective-black absorbers. Transparent heat mirrors transmit solar radiation and reflect thermal radiation; selective absorbers absorb solar radiation and have low infrared emissivity. We have prepared both transparent heat-mirror films (TiO2/Ag/TiO2 Sn-doped In2O3 and Sn-doped In2O3 microgrids), and cermet absorbers (MgO/Au) that have excellent wavelength-selective properties. In addition, the cermets promise to be stable at the elevated temperatures required of the absorbers.
