Abstract

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.
