Vide infra: Two boron-dipyrromethene (BODIPY)-type infrared sensitizers are investigated for use in titania-based dye-sensitized solar cells (DSCs). The DSCs use a solution of dimethylferrocene (Me2 Fc) in nitromethane as electrolyte. The titania conduction band edge is fine-tuned by adding lithium ions from LiTFSI, while the choice of dimethylferrocene as redox shuttle provides the ideal driving force for dye regeneration, allowing the BODIPY-based DSCs to reach unprecedented quantum efficiencies in the near-infrared.
