Fig. 5: Thermal insulation performance of ST-OPVs as windows.

The temperature (°C) changes are recorded by a Fluke infrared thermal imaging camera under the IR mode. The colored scale bars represent temperature from 15 to 60 °C. a The temperature of the object before illumination. The temperature of the object after 10-min solar simulator illumination with different windows, (b) without, (c) glass, (d) 11-nm Ag, (e) 40-nm TeO2, and (f) ABPF based ST-OPVs.
