Flexible, solid-state, dye-sensitized, solar cells (DSSC) combine the benefits of lightweight flexibility and the stability of non-liquid containing devices. One of the major challenges for the fabrication of flexible solid-state DSSCs is the fabrication of good quality TiO₂ films at low temperature. In this work, atomic layer deposition (ALD) and electrophoretic deposition (EPD) are used to deposit dense and mesoporous TiO₂ films at low temperatures, respectively. The amorphous thin films fabricated by ALD are shown to be pinhole-free even at a low thickness of 10 nm, and they have also shown to give rectifying behavior. Using these low-temperature film deposition methods, flexible solid-state DSSCs on polymer substrates are fabricated for the first time with an efficiency of 1.93% upon optimization of film thicknesses. This work shows that the important milestone of flexible, solid-state DSSCs has been reached.
