Western European single-glass photovoltaic curtain wall application

Photovoltaic Curtain Wall generates energy in the building implementing solar control by filtering effect, avoiding infrared and UV irradiation to the interior.

The VPV curtain wall consists of a piece of CdTe-based PV laminate glass, an air cavity, and a sheet of vacuum glazing. The solar cells are etched into strips by lasers, and the transmittance of the VPV sample can be adjusted by changing the arrangement density of the strip solar cells.

PV IGU Curtain Wall System manufacturing with double or tripple glazzed units for BIPV solar facade integration.

According to the literature review, VPV curtain walls exhibit significant potential for energy savings owing to their excellent thermal insulation performance . Furthermore, the shading effect of PV cells can alleviate discomfort glare and enhance occupants' visual comfort .

Building exterior glass curtain walls serve as the interface between the indoor artificial environment and the outdoor natural environment, fulfilling the essential function of thermal insulation while also playing vital roles in providing daylighting and views .

It is observed that the VPV curtain wall with 10%, 0%, and 50% PV coverages of daylight, view, and spandrel sections has the highest average DGPs of 40.1%. By increasing the daylight section's PV coverage to 50%, the average DGPs decrease by 11.5%, while increasing the spandrel section's PV coverage to 90%, the DGPs only reduces by 2.5%.
