What GraphEnergyTech does
GraphEnergyTech is a Lausanne-based private materials company, with a secondary office in Cambridge, UK, that develops a graphene-based conductive paste designed to replace traditional silver electrodes in photovoltaic (PV) cells and printed electronics. The company's core product, Conductive Graphene Paste, is engineered to achieve >150,000 S/m conductivity and <1 Ω/sq sheet resistance, and to be drop-in compatible with screen printing, slot die coating, blade coating, and jetting deposition on both roll-to-roll (R2R) and sheet-to-sheet (S2S) production lines, spanning perovskite, tandem, and silicon PV cell architectures. The company claims up to 90% electrode cost reduction and 97% lifecycle CO2 reduction compared with metal electrode alternatives, positioning the technology against silver resource scarcity and the environmental footprint of conventional PV metallization.
The business model is a direct enterprise hardware-sales motion: GraphEnergyTech sells its conductive paste to solar cell manufacturers (primary segment) and printed electronics producers (secondary segment), with pricing handled on a quote basis via a 'Contact Sales' / sample-request engagement rather than published list pricing. The company is 1-10 employees, was founded in 2022, and has raised approximately CHF 1.1 million in disclosed seed funding led by Aramco Ventures in August 2024, with additional capital engagements from CES (October 2024) and Tech4Regeneration (March 2026). No production customers, revenue figures, patents, or formal certifications are publicly disclosed, indicating an early commercial stage with technology validation but limited scale signals.

GraphEnergyTech competitors and assessment
Company assessmentDirect peers
- Vorbeck Materials: Vorbeck Materials is a developer of graphene-based conductive inks and pastes for electronics and energy applications. It is directly comparable as a graphene conductive paste specialist targeting similar use cases including printed electrodes and energy devices.
- Haydale Graphene Industries: Haydale is a UK-based graphene materials company producing functionalized graphene inks, pastes, and coatings. It is a direct peer in graphene-based conductive pastes and has overlapping target applications in printed electronics and energy.
Broad incumbents
- Heraeus Photovoltaics: Heraeus is one of the dominant global suppliers of silver pastes for solar cell metallization. It is the incumbent that GraphEnergyTech is most directly trying to displace, with overlapping customers (PV cell manufacturers) and overlapping chemistry expertise.
- Sumitomo Metal Mining (PV paste business): Sumitomo Metal Mining supplies silver and silver-alloy pastes for PV electrode applications and is among the leading incumbent metallization paste suppliers. It competes for the same silver-replacement opportunity at large PV cell manufacturers.
- DuPont Silver Pastes (Solamet): DuPont's Solamet silver pastes are widely used in PV cell manufacturing and the franchise is being actively adapted for low-silver and perovskite cell architectures. It is a broad incumbent competing in the same electrode materials category.
- Sun Chemical (导电 inks / pastes division): Sun Chemical supplies conductive inks and pastes, including silver and carbon-based formulations, into electronics and energy markets. It is a broad incumbent in conductive inks with overlapping customers and formulation know-how.
- Graphenea: Graphenea is a leading graphene materials supplier producing graphene powders, dispersions, and inks for industrial R&D and applications. It is comparable as a graphene materials provider that could supply or compete with GraphEnergyTech's upstream inputs.
Emerging players
- C3Nano: C3Nano develops silver nanowire-based transparent conductive inks and films as alternatives to silver pastes and ITO. It is an emerging alternative-metallization player targeting similar PV and printed electronics customers with a different chemistry.
