What is the surface charge on N719 or other dyes used in Dye-sensitized solar cells?

All the dye particles are either cationic, anionic or nonionic in nature. However most of the dyes are either cationic or anionic. How about dyes used for Dye sensitized solar cells like N719 or D719

How can I carry out activation of Pt as a catalyst in DSSCs?

We normally anneal drop coated or sputtered Pt (H2PtCl6) for its activation as catalyst in DSSC. The process is around 400 C for 20-30 min. Is there any other way by which Pt can be activated...
