Abstract

Flexible dye sensitized photovoltaics (f-DSPVs) based on plastic substrates have attracted significant interest due to their light-weight, flexibility, and compatibility with roll-to-roll processing, as well as their potential application to ubiquitous power sources. However, f-DSPVs exhibit inferior power conversion efficiencies (PCE) compared to conventional DSPVs since the fabrication process must be conducted at a low-temperature (≤ 150°C) to prevent thermal damage of the plastic substrates, which generally results in poor interconnection between the TiO2 nanoparticles. Numerous novel low-temperature manufacturing approaches for flexible photoanode and counter electrode have been developed. In this review, current progress on low temperature strategies for f-DSPVs technology are discussed.
