Group 4 Photovoltaics (G4PV) SA
We empower the future of extra-terrestrial energy by combining advanced AI training with space-grade flexible photovoltaics. Leveraging high-throughput AI simulation, data-centric modeling, and material innovation, we accelerate the discovery and deployment of ultra-lightweight, radiation-resistant flexible solar devices.
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, 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.
Our Professional Team
Prof. Paul Dyson
Principal Scientist
Paul J. Dyson received his PhD in 1993 from the University of Edinburgh, remaining there for a further year as a postdoctoral fellow, and then moving to Imperial College, where he obtained a Royal Society University Research. His research focus on organometallic chemistry at the interface with medicine, catalysis and material science.
Prof. Mohammad Khaja Nazeeruddin
Principal Scientist
Nazeeruddin is a Em Professor of Chemistry at the EPFL Sion campus, and his current research at EPFL focuses on Perovskite Solar Cells and Light-emitting diodes. Based on the Career Long Impact, Nazeeruddin has been enlisted as one of the Top 2% Most-Cited Scientists in the world from the list published by Stanford University in October 2022.
Lianghui Li
CEO
Lianghui Li obtained his bachelor in College Chemistry, Nankai University. He is currently pursuing his PhD in the Laboratory of Organometallic and Medicinal Chemistry (LCOM), EPFL. His research focuses on functional organic molecules and their applications in pharmaceuticals and materials science.
Shun Tian
CTO
Shun Tian obtained his Bachelor's degree from the School of Optoelectronics at Beijing Institute of Technology (BIT) in 2019. In 2022, he obtained his Master's degree from the College of Optical Science and Engineering at Zhejiang University. Currently, he is a PhD candidate in the Laboratory of Organometallic and Medicinal Chemistry (LCOM) at the Swiss Federal Institute of Technology in Lausanne (EPFL). His research focuses on perovskite-based optoelectronic devices, including solar cells and light-emitting diodes.
