“…The areal power density for this sample was increased to 2.04 W/cm 2 at 6 V and a saturation temperature of 141 °C was achieved. Depending on the referred reference (literature or commercial data), THs with power densities in the ranges of 0.077-0.15 and 0.4-0.77 W/cm 2 can be used for defogging and deicing applications, respectively [68,[86][87][88]. The amount of heat generated by the heater due to Joule effect is depending on the heater material, electrode geometry, the sheet resistance of the coating, and the level of operating voltage.…”

Double layer glass/fluorine-doped tin oxide (FTO)/aluminum-doped zinc oxide (AZO) multifunctional thin films were achieved via ultrasonic spray pyrolysis (USP) method without employing a post-deposition annealing. Transparent heater and near-infrared heat reflection behaviors were investigated. The samples were characterized in terms of their structural, morphological, optical, and electrical properties. The top AZO layer exhibited a polycrystalline structure without any preferred orientation. The double layer structure showed very high average transmittance (87%, 400-700 nm) in the visible and reflectance (55%, 2500 nm) in the near-infrared, regions. In addition, the sheet resistance and resistivity of the film were measured as 14.85 (Ω sq −1 ) and 1.78 × 10 −3 (Ω cm), respectively. The saturation temperature, response time, surface temperature uniformity, areal power density, and thermal resistance values were found to be 111 °C, 174 s, 11.42%, 0.299 W/cm 2 , and 282.8 °C cm 2 W −1 for a sample with an active area of 31.5 cm 2 and input voltage of 9 V. In addition, dryice cooled samples (−25 °C) showed impressive deicing performance depending on the input power. In case of 12 V, all ice was defrosted, and water droplets were evaporated within 2 min and 10 s. During this process, a heating rate of ⁓43 °C/min was achieved.
