Any one who has an experience to make ITO/PCBM thin film by spin coating?

Resistor definition in Piezoelectric bimorph with ANSYS workbench

Hello, good day! I am trying to simulate similar bimorph piezoelectric harvester with below commands. However, the output power doesn't change with resistor value. Please help to find the reason. ET,10,CIRCU94,0 !SET UP RESISTOR R,1,100000 !RESISTANCE VALUE TYPE,10 !SET ELEMENT TYPE E,1,2 !CREATE RESISTOR BETWEEN NODES 1 AND 2 Thanks in advance Regards,

Yangping Wen

this was closely related materials or solvents.

Dear colleague,

You can try to dissolve PCBM with chlorobencene. Additionally you need to know that is very important to do firstly an UVO treatment on the ITO surface in order to have a good wettability of the PCBM solution before spinning.

Good luck!

Dear Mario Alejandro Mejia Escobar,

Thank you for your advice. Actually we also use the UVO treatment on the ITO surface. As you said I should try to dissolve PCBM with chlorobenzene which can dissolve PCBM easier than toluene. And do you think I should change the substrate as well?

Hi again,

I dont think so. ITO is a nice substrate. On the other hand, have you try to do a dinamic spinning?
