How do you adjust the speed of spin coating in order to give thickness around 30 nanometer on thin film of PEDOT:PSS solution?

I would like to know how the way to adjust speed of spin coater, in resulting thickness of PEDOT:PSS around 30 nm. if anybody have any experience with that, it will be my pleasure. Thank you
