Group 4 Photovoltaics (G4PV) SA

G4PV has ambitious plans to launch a 20 MW Perovskite Solar Cells Pilot Production Line in Sion, Switzerland.

The pilot line will be designed to manufacture both perovskite and perovskite/Si tandem solar panels. The panels are designed to achieve impressive performances, with perovskite tandem panels surpassing, respectively, 23% and 30% efficiencies. The intrinsically low cost and low energy deposition techniques employed will yield electricity production at less than 0.02 Euro/kWh. Moreover, G4PV is committed to sustainability, with a significantly lower Carbon footprint compared to traditional Si PV panels. The G4PV products can also be fully recycled at the end of their lifecycle.
