Carbon paste is a graphite/carbon-black 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 photo-electrochemical devices, such as perovskite solar cells and dye sensitized solar cells.
Coating process: screen-printing, slot-coating (doctor-blade)
Aspect : black viscous paste
Treatment :<200°C for 30 min (e.g., 100°C for 15 min)
Carbon composition: ≤20 μm graphite particles and carbon black nanoparticles
