BIPV windows refer to the integration of electricity-producing PV elements into a window or building façade system, most commonly glazing or spandrel panels. There are several types of BIPV glazing systems available today, ranging from light redirecting layers that direct solar radiation to strategically placed PV cells, to semi-transparent PV coatings (STPV) and traditional opaque PV cells integrated into selected area of laminated glass. Compared to other advanced window technologies, BIPV glazing is distinguished by the ability to transform a portion of the incident solar irradiation into useful electrical power through the photovoltaic effect, while at the same time contributing to the regulation of solar heat gain and daylighting glare by reducing the solar transmittance through the glazing PV. BIPV windows provide a very promising alternative window choice for buildings striving to meet zero net energy goals, especially for buildings that are characterized by the large window to wall ratio (WWR) and limited useful roof area.
