Elcocarb G/SP

Elcocarb G/SP is multi-graphite paste aimed at the deposition of metal-free, electrically conductive layers by screen-printing or slot-coating techniques. It can be used for the fabrication of carbon electrodes in various electrochemical devices, including new generation photovoltaics.

Elcocarb G/SP contains graphite particles in a 1–20 µm range. Firing at 400°C leads to a highly conductive, hydrophobic and non-metallic layer that remains porous. The chemical inertness of this layer enables a broad range of material compatibility with no risk of corrosion.

Carbon films obtained from Elcocarb G/SP demonstrate excellent adhesion on a variety of substrates, such as coated glasses and ceramic surfaces. They can ideally replace glass counter-electrodes in monolithic solar cell assemblies when used in conjunction with our Ti-Nanoxide and Zr-Nanoxide products.

Those layers also feature a very good electron transfer rate to iodide-based Dye Solar Cell electrolytes like our Iodolyte and Mosalyte products.
