Attempts have been made to replace the components with new electrode materials, alternative sensitizers and different types of electrolytes. In most cases studies were aimed at achieving advanced properties and applying DSSC in order to meet the requirements of commercial applications and/or to reduce the production cost. An important issue in cost reduction is the fabrication of DSSC on flexible, transparent, conductive plastic substrates [190-192]. The nanocrystalline Ti02 film is considered to be the most promising material for the electrode of dye-sensitized solar cells to generate high performance [193-195]. 

In another study, Maeda et al fabricated transparent conductive films by air spraying enriched metallic SWNTs (from the amine-assisted post-production separation ) on to both quartz and PET substrates. The sheet resistances in the films on PET were 690 Q sq at an optical transmittance of 81% (550 nm) and 9000 Q sq at 97% (550 nm), which represented reductions by a factor of 20 in comparison with the performance in films of non-separated SWNTs. The same group also found that the effectiveness in the separation for metallic SWNTs is determined by the use of different amines at various concentrations. The proportion of metallic SWNTs against semiconducting SWNTs in the... 

Although they have not yet been applied to the production and screening of photoelectrolysis materials, we will briefly mention some other approaches to produce metal oxide libraries using well-established thin film deposition techniques (meant here to include physical vapor deposition, sputtering, pulsed laser deposition, and molecular beam epitaxy). These techniques have been used for the production of combinatorial metal oxide libraries in the search for more effective luminescent materials [90,91], transparent conducting oxides [92,93], and dielectrics [94,95]. It would presumably be straightforward to apply the same techniques to the production of material libraries to be screened for photoelectrolysis activity.
