GraphEnergyTech supplies graphene‑based carbon electrode inks that replace metal electrodes in photovoltaic modules and printed electronic devices. The inks deliver high conductivity (over 150,000 S/m) and low sheet resistance (<1 Ω/sq) while cutting electrode costs by up to 90% and reducing lifecycle CO₂ emissions by 97%, and they are compatible with standard printing processes and existing roll‑to‑roll or sheet‑to‑sheet production lines.

Problem
Traditional photovoltaic and printed electronics manufacturing rely on metal electrodes, which are expensive to produce and generate significant CO₂ emissions throughout their lifecycle. The high cost and environmental impact of these metal components limit the scalability and sustainability of solar and flexible electronic products.
Solution
GraphEnergyTech offers graphene-based carbon electrode inks that replace conventional metal electrodes in photovoltaic cells and printed electronic devices. The graphene electrodes provide conductivity up to 150,000 S/m and sheet resistance below 1 Ω/sq, delivering performance comparable to metal while being up to 90 % cheaper. By using a carbon material with a 97 % lower lifecycle CO₂ footprint, the technology reduces emissions by 0.86 kg CO₂‑eq per kWp of generated power. The inks are compatible with perovskite, tandem, and silicon solar cells and can be applied using standard printing processes such as screen printing, slot‑die coating, blade coating, and jetting on both roll‑to‑roll and sheet‑to‑sheet lines, enabling seamless integration into existing production lines.
Target Audience
Primary customers are manufacturers of photovoltaic modules and printed electronic devices seeking lower‑cost, high‑performance electrode solutions that can be integrated into existing printing and coating production lines.
