How does a transparent PV module work?
When sunlight transmits through the first layer of HISG (i.e., the transparent PV module), the rest of the light is reflected to the back of the transparent PV module by the high reflectivity heat insulation film (i.e., the second layer). The amount of power generated increases when the transparent PV module absorbs the reflected light.
How does photocatalyst layer coating affect HISG glass?
The photocatalyst layer coating on the HISG surface changed the surface properties of the glass, creating the water contact angle of only 6°, which was super hydrophilic. During rain, this coating produced a water film and stains were easily removed, thus achieving self-cleaning.
Does HISG block radiation and conductive heat?
However, the multi-layer structure of HISG blocked radiation and conductive heat; consequently, the temperature in the HISG House was 44 °C, which was approximately 11° lower than the 55 °C temperature in the Ordinary House. In summary, simulation software again demonstrated excellent heat insulation effects for HISG.
