The right choice for a more efficient and longer shelf life OPV device

Genes’Ink patented Helios'Ink solutions can be used for electrodes manufacturing or charge transport layer deposition in OPV cells:
- Busbars
- Electrodes
- Charge Transport Layers
Key Benefits:
- High conductive performance (1,6 to 2,5 time silver bulk)
- Reduction of coverage cost
- Printing on many different flexible plastic substrates (PET, PEN, KAPTON, Verre, Polycarbonate, Paper, Verre ITO, Ag NWs layer, Active layer)
- Low/No curing process for printing on flexible substrates : IR, Photonic, Industrial Oven, Conveyor Oven, Tunnel furnace
- Improved cell efficiency (PCE>10%)
- High transparency (>90%)
- Protection against oxidation (PCE<10% after 2 000h)
- Protection against aging due to UV exposure
- Smoother surface
