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, 27% and 35% efficiencies. The intrinsically low cost and low energy deposition techniques employed will yield electricity production at less than 0.02 €/kWh.

High efficiencies

High efficiencies beyond that of traditional silicon photovoltaics.

Low-cost

Low-cost production as the materials and manufacturing processes are comparably inexpensive.

Flexibility

Flexibility and versatility as the panel can be made in glass or plastic, the latter being 100 times lighter than current commercial silicon photovoltaics. 

Rapid production

Rapid production as low-energy solution-based processes are used.

Applications

We target utility scale PV, Building integrated PV and Vehicle Integrated PV.

G4PV

The Group 4 Photovoltaics (G4PV) is a spin-off from EPFL/EPFL-Valais, created after many years of research on perovskite solar cells under the leadership of Profs. Mohammad Nazeeruddin and Paul Dyson.
Perovskite solar cells use elements from Group 4 of the periodic table and convert sunlight into electricity. At the end of life, the elements can be recycled to provide circularity.
Perovskite solar cells are thin and lightweight and can be applied on both inflexible (glass) and flexible (transparent plastic) supports.

Administration

Jacqueline Morard is currently the secretary of the laboratory of organometallic and medicinal chemistry at the Ecole Polytechnique Federal de Lausanne that is directly dependent on the Federal Department of Home Affairs of Switzerland. She was born in Zurich in 1964 and received her diploma in office management in 1985. After her training she moved to the French part of Switzerland where she took over a job as a junior secretary with Plastag in Eclépens. In 1985 she worked with Siemens where she evolved steadily during 14 years to an executive secretary. In 2000 she joined the EPFL, more precisely the laboratory GECOS that has dealt with environment. After the retirement of her boss she joined the Research Center in Plasma Physics within the EPFL as an assistant to the director where she worked until the 2008.
