binder for thin films

[corinne durand]

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

Hi corinne

to the Surface Engineering Forum.

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

[corinne durand]

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
corinne
