Hi
Could anyone tell me the procedure for the cleaning ITO substrates for organic solar cells?
This was my procedure, but I always had dirty spots on the glass and of course shortcuts in the cell.
1) cleaning in a deionized water + detergent (Hellmanex) mixture in ultrasonic bath (60 min)
2) 30min in deionized water in ultrasonic bath
3) then 30 min in ethanol (absolute) in ultrasonic bath
4) 15 min in acetone in ultrasonic bath
5) drying with nitrogen
What have I done wrong?
Thanks
