Can glass curtain walls be used for solar power generation

Are photovoltaic curtain walls a good choice for high-rise buildings?

A multi-dimensional evaluation of the semi-transparent photovoltaic glass curtain wall and the LOW-E glass curtain wall is conducted. The study analyzes the advantages of using photovoltaic curtain walls in high-rise buildings regarding energy consumption, lighting comfort, cost, and energy efficiency.

Do photovoltaic curtain walls save energy?

For instance, in areas with abundant solar radiation, low-AVT and high-PCE photovoltaic curtain walls (like those with AVT of 0.4 and PCE of 12 %) can greatly cut cooling energy use while slightly raising heating and lighting energy consumption. Moreover, they boost electricity generation without significantly increasing manufacturing costs.

Can Photovoltaic Glass be used as curtain walls?

Fig. 1. Spectrum of semi-transparent tandem photovoltaic cells . Using photovoltaic glass as curtain walls involves a simplified method, treating each room facade as a continuous glass panel for description and calculation. Low-e and Clear glass are selected from the NFRC - compiled IGDB (International Glazing Database).

How much does photovoltaic curtain wall glass cost?

Cost-wise, photovoltaic curtain wall glass costs 477.177/m 2, lower than the 549.815/m 2 for solar control glass with the same effect. The study suggests using Low-e glass for floors 1–20 and photovoltaic glass above to reduce LCOE to 0.894/kWh.
