binder for thin films
I work actually on spin coating, and I would like to make thin film of CuInS2 using this technique.
I'd like to use binder to improve my process, but I don't where to start.
So, can somebody help me? It'd be very nice
Thanks

Must admit to not knowing much on spin coating technology Ashamed0002 Could you give us a bit more information?

OK,

So I would like to make uniform coating of CuInS2 (thickness 1.5-2 micrometer) on a glass substrate.
Actually I use an aqueous solution of CIS nanoparticles, but the obtained coatings are not uniform (visual aspect, thickness).
I already tried different concentrations, different spin programs, but nothing changes.
I hope, that you'll can help me with these new informations.

Thank you
corinne

Hi corinne

Have you tried alcohol (ethanol or isopropanol) carriers instead of water?

A few links on the subject of spin coating, though I suspect this will probably be of more use to those of us that are not too familiar with the process.

(Sorry all links now dead)

Thank you for your answer.
I had already read these different articles...
But I hope that I will receive other advices from this forum

Thanks

Hi,

How about using electrophoretic deposition using the existing suspension solutions (since your glass is non-conductive, you will need to using a metallic auxilary working electrode next to the glass).

With a bit of experimenting, you will instantly know which electrode will be the anode (depeding on the charge state of your suspension solution).

OK,

It seems to be a good idea.
I am going to make research about this pocess, but could you indicate to me some puplications and internet links which could help me, because I have never used this process before.

thanks
