Glass affects photovoltaic power generation

What is heat insulation solar glass (HISG)?

Heat insulation solar glass (HISG) is a type of multifunction PV module. HISG has a considerably low shading coefficient and U value. HISG can reduce air conditioning and heating energy consumption in buildings. HISG can replace any type of glass installed in a building. HISG is a safe construction material.

Do two types of glass affect thermal environments in Taipei?

Aside from differences regarding the glass installed in the two houses, both houses exhibited identical condition. This study observed the effects that two types of glass had on thermal environments within buildings under climate conditions found in Taipei.

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.

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.

Are HISG and single-layer tempered glass energy-saving?

To compare the efficacy of HISG and single-layer tempered glass that is commonly used in buildings, this study tested the power generation, heat insulation, and air-conditioner and heater energy-saving effects of HISG and single-layer tempered glass, using experimental houses for realistic measurements.
