Ossila's ITO substrates can be used to prepare organic photovoltaic cells and organic light emitting diodes. They are manufactured from commercial grade ITO used in the flat panel display industry in order to endure high consistency and very low defect rates. Each substrate has six ITO fingers which when used with an Ossila evaporation shadow masks creates six independent devices with dimensions of 1.5 mm x 3 mm. An additional cathode strip allows easy connection of both anodes and cathodes by attachment of electrical legs. The substrates are packed in stacks of 20 individually separated by pieces of cleanroom paper. A simple cleaning procedure then provides a clean and hydrophilic surface perfect for spinning PEDOT:PSS.

Use:To prepare the substrates for use we recommend cleaning in a solution of hot sodium hydroxide (NaOH) which will both help remove any dust and also provide a hydrophilic surface without the need for a plasma or UV clean (note that some materials/solutions particularly close to the wetting envelope may still benefit from a plasma clean). We use the following cleaning routine for OPVs and OLEDs, however please note that exact times will depend upon the power and temperature of the sonic bath and that excessive sonication can also increase the resistance of the ITO surface.
- Sonicate in 10% NaOH solution for 5 mins using a hot bath
- Rinse thoroughly in hot water
- Sonicate in fresh 10% NaOH solution for 5 mins using a hot bath
- Rinse thoroughly in hot water
- Store immersed in water until required
- N2 blow dry
