The front layer is conductive SnO2, and I believe plays no PV other than being a transparent conductor. The back layer does play an active part in
the PV process, and must be carbon or platinum on SnO2. In both cases the doping of the ITO or SnO2:F layer is to get to conduct.
Note that the TiO2 is not just ceramics grade stuff, but Degussa P25 nano-particle material which has a high anatase phase content, or be formed in
place from a titanium alkoxide.
Ive not attempted creating any kind of transparent conductive coating (i have enough trouble making any kind of coating conductive but are electrolytes completely out of the question for this kind of application ?
perhaps a very corse grid like current colector with the whole pannel immersed in an electrolyte that is non reactive with the PV cell ?
It already has an electrolyte, a non-aqueous iodide-iodine containing one; where are you putting the second one? Water and O2 degrade the system, the
anatase TiO2 is good at oxidising organics in the presence of O2 and light. Read the articles linked to at http://www.solideas.com/solrcell/coatglas.html#Articles
