Thin-film solar glass curtain wall

What are some examples of photovoltaic curtain walls?

Examples include colored solar panels in Denmark [ 27 ], Building-integrated Photovoltaics (BIPV) walls in Italy [ 28 ], and the Ekoviikki Sustainable City Project in Finland [ 29 ]. Currently, research on photovoltaic curtain walls is still in its early stages, primarily centered around the performance evaluation of such systems.

Does a curtain wall reduce heat gain from solar radiation?

It can be found that the heat gain through the curtain wall decreases from 394.95 W under 0.1 PV coverage ratio to −144.03 W under 0.9 PV coverage ratio. The increased PV coverage ratio means that a larger area of PV cells is covered with the glazing, thus considerably reducing the heat gain from solar radiation.

How does a photovoltaic curtain wall work?

A photovoltaic curtain wall coupled with an air-conditioning system is designed. Curtain wall cooling and supply air reheating are achieved using heat recovery. System performance is evaluated, taking an office in hot-humid summer as a case. The system increases power output by 1.07% and achieves 27.51% energy savings.

Do photovoltaic curtain walls improve the cost-effectiveness ratio?

After sensitivity analysis of the cost of photovoltaic curtain walls and the efficiency of solar panels, it was found that as the cost increases, the economy of photovoltaic curtain walls gradually deteriorates, and improving the efficiency of solar panels can improve the cost-effectiveness ratio of each facade.
