GraphEnergyTech

GraphEnergyTech is a Swiss deep-tech company developing advanced graphene-based conductive pastes and inks to replace silver and other metal electrodes in solar photovoltaics and printed electronics. Founded in 2022 in Lausanne, Switzerland, by Dr. Thomas Baumeler, the company's graphene electrode technology achieves conductivity exceeding 150,000 S/m and sheet resistance below 1 Ω/sq, enabling up to 90% cost reduction versus metal alternatives while cutting lifecycle CO₂ emissions by 97%. Their materials are compatible with perovskite, tandem, and silicon PV cells, and integrate with screen printing, slot die coating, blade coating, and jetting processes for both roll-to-roll and sheet-to-sheet manufacturing. GraphEnergyTech targets solar cell manufacturers and printed electronics producers seeking sustainable, cost-competitive electrode solutions.
