G4PV

The Group 4 Photovoltaics (G4PV) is a spin-off from EPFL/EPFL-Valais, created after many years of research on perovskite solar cells, with the support from Prof. Mohammad Nazeeruddin and Prof. 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.
Currently, the company is working on AI training (build high quality dataset like RLHF, HLE, etc. in physics, chemistry, and material science), Perovskite materials preparation (transport, interfacial, precursor, etc.), custom services for profit/non-profit insititues, and flexible devices.
