How we can prepare SnO2 (tin oxide) paste for screen printing from commercially available nano-particles (18-20 nm size)?

I am familiar for making paste out of Al2O3 nano-particles with TERPINOL AND ETHYL CELLULOSE, but was wondering if any one is familiar with a direct method to prepare SnO2 paste. Thanks.

How can I reduce the aggregation of organic dyes on TiO2 surface for DSSC?

Possible options are additions of CDCA-coadsorbate, and co-sensitization. I have tried both options, CDCA do not help a lot by increasing to 100x compared to amount of dye. Co-sensitization...

Does anyone have experience with Dimethyl terephthalate or terephthalic acid photophysics and photochemistry?

Most of the literature search for me result into hits which are either done in 1970's or late 80's. I am interested mainly in knowing about transient absorption and photophysical nature singlet,...
