Infrared-reflecting selective surface materials which can be useful for architectural and/or solar heat collector windows
Results have shown that thermal radiation transport contributes significantly to space heating losses through architectural windows. The losses can be reduced by the use of selective surface materials deposited on the window glass and/or plastics. The ''selectivity'' of these materials refers to selective optical properties that are, primarily, high infrared reflectivity and high visible transmission. This review of selective surface materials deals mainly with architectural windows, but will have relevance to solar heat collector windows. A discussion of the wavelength selective properties of certain semiconductor and metallic films that show desirable properties for prospective window coatings is presented. A brief discussion follows on materials suitable for protecting a selective film from mechanical and/or chemical degradation without altering the selective optical properties. The problem of bonding selective surface materials to plastics, without altering the selective aspects of the films is discussed. The basic physics of selective infrared-reflecting doped wide-band-gap semiconductors, particularly SnO/sub 2/ and In/sub 2/O/sub 3/ when doped with certain impurities, is reviewed.
