    Posted: 06 November 2009 at 5:23am

Hi

I'm using P25 TiO2 nanoparticles to prepare TiO2 film on FTO substrate for DSSC working electrode via doctor blade. I prepare the TiO2 paste in ethanol, I'm facing a problem ie, when i go for multiple coating in order to increase the thickness of film, the film adherence is poor or cracks develop and the film starts to peel off, can anyone suggest a method for preparing thicker films (~10micro meter) via doctor blade using some other solvent or conditions.
