Transparent heat-mirror films of TiO2/Ag/TiO2 for solar energy collection and radiation insulation

Abstract

Transparent heat-mirror films of TiO2/Ag/TiO2 on glass with a visible transmission of 84% (at 0.5 μm) and an infrared reflectivity of 98–99% (at 10 μm) have been fabricated by rf sputtering. Initial tests indicate that the films are thermally stable in air at 200°C and inert to water attack. Because of their excellent optical properties and apparent stability, these transparent heat-mirror films offer great promise for use in solar-thermal power conversion and as transparent thermal insulators.

Optimal Design of Hybrid Energy Systems for Small Power Generation

“…The glass globe must be thin and have high transmissivity for light in the visible wave lengths; it should be internally coated to maximize reflection of radiation from the receptor surface (7). As in a light bulb, the glass enclosure will get hot and must be insulated at the base.…”

ZnS/Ag/ZnS coating as transparent anode for organic light emitting diodes

“…Another alternative to ITO as transparent conductors is the use of dielectric/metal/dielectric (D/M/D) multilayers, which suppress the reflection of the metal layer and achieve selective high transparent effect [14]. In 1998, Bender et al [15] reported ITO/Ag/ITO (IMI) structure with higher conductivity.…”
