Video: How to Clean Substrates for Photovoltaic or OLED Fabrication

This video provides a walk through guide on how to clean substrates for photovoltaic and OLED fabrication.

Achieving a clean substrate is an important first step to fabricating good devices as it allows subsequent layers to be kept clean and defect free.

For effective cleaning of substrates, follow the below steps:

  • 5 minute sonication in hot Hellmanex III
  • Rinse thoroughly twice in hot de-ionised water
  • 5 minute sonication in IPA
  • Rinse thoroughly twice in hot de-ionised water
  • Dry with N2 gun
