Actually, PFIL on the electrode assembly offered a suitable
electrochemical microenvironment for electrochemical reaction; in
this case, it was not absolutely electrolyte free. Thus, it also hints
functionalized IL could be used as solid-state electrolyte for some
specific applications, such as solar cells. Figure 4.13b shows a full
solid-state, flexible, dye-sensitized solar cell (DSSC) based on novel
ionic liquid gel (PVA-g-VIC4Br), organic dye, ZnO nanoparticles, and
CNTs thin film stamped onto a polyethylene terephthalate (PET)
substrate [55]. It would pave the way for the development of a
continuous roll-to-roll process for the mass production of flexible
and lightweight DSSCs.
