What is semi-transparent photovoltaic (STPV) glazing?
In window-style installations, semi-transparent photovoltaic (STPV) glazing replaces traditional windows, converting solar energy directly into electricity . Li et al. conducted an investigation into the thermal and visual properties, energy performance, and financial aspects of STPV façades.
Can high transmittance glass improve lighting?
It is important to note that while high transmittance ratio glass can enhance lighting, it is also essential to consider the potential for interior glare. Glare can adversely affect occupant comfort and may diminish the efficiency of building use.
How do gasochromic windows respond to infrared rays?
Gasochromic (GC) windows respond to infrared (IR) rays by implementing chemochromic coatings that will be triggered by hydrogen or oxygen gases [40,57]. Since another system should pump the gas and activate gasochromic material, GC windows are considered active smart windows .
Are translucent Photovoltaic windows a good option for BIPV buildings?
It has a number of limitations: cost, low efficiency, lack of proven stability, lack of aesthetic appeal and awareness, and so on. However, among other things, translucent photovoltaic windows can generate electricity with reduced air conditioning loads and can improve the natural lighting environment inside BIPV buildings.
What is a double layered STPV window?
This dual-layered window comprised a single-layered STPV window paired with a conventional window separated by a vacuum air layer. The double-pane STPV window was evaluated for its thermal insulation and power generation performance compared to the single-pane configuration used in earlier studies.
