The most used electrolyte in DSSC applications is liquid. I think that solid electrolyte is more suitable for manufacturing of this kind of solar cells.

Thanks for sharing Ajay. If I may interject, In many technical descriptions of the anatase - dye (where metal in dye can be easily oxidized,see dyesol, thus the need for solvent based dyes-inneficient also because of agglomeration aggregate) system, it never discusses an electrical conductivity but stresses the hopping of electrons toward the electrolyte with a mesoporous structure 2-50nm. These micro architectures of the DSSC at approx. 11 microns thick of hopping electrons still sound like stone age technology?? When you have an optimized anatase that will create holes with the electrons moving at speeds of what? 10 sup neg 12 speeds??, most of them will fall back into the hole before being transferred through non conductive mesoporous space. But dont get me wrong, DSSC is a powerful technology with great potential, where electrons still can get through and efficiencies of 11% can be obtained. Once a microporous structure can be made hybrid with not dye but amorphous metal within a thin film of a molecularly crystalline ordered anatase composite at the atomic level and exhbit films of less than 1 micron can you obtain real conductivities where a solid electrolyte thin film can be considered. At this point because of transparencies one will be able to construct multiple layers (I think that they call it multiple junction) and the efficiencies will dictate that this technology is for real! Applied roll to roll on polymeric substrates and not glass. Environmentally friendly and mostly COST effective where they can be sold because people will buy them!
