| Layers of high-conductive CLEVIOS™ P, i.e. CCP105D, CLEVIOS™ PH V4, CLEVIOS™ PH 500, CLEVIOS™ PH 510 are cost-efficient alternatives to substitute ITO as transparent conductive electrodes in OLEDs and OSCs. To compensate ohmic losses in large area devices the conductive polymer can be combined with printed metallic bus-bar lines additionally.
The thickness of the CLEVIOS™ P layer after spin-coating onto ITO is determined by several parameters:
- spin speed
- acceleration
- spin time
- design of the spin-coater
- substrate size
- quality of the pre-conditioning of the substrate surface.
The pre-conditioning of the ITO glass strongly affects the ability to uniformly disperse CLEVIOS P onto the substrate surface. Therefore, no general rule can be given to determine at what spin speeds specific layer thicknesses will result. |
