Molecular design of squaraine dyes for efficient far-red and near-IR sensitization of solar cells
The introduction of short carboxyl anchoring groups into anilino-squaraines resulted in a much improved photosensitization on nanocrystalline TiO2 electrode over far-red/near-IR region, yielding a maximum monochromatic incident photon-to-current conversion efficiency of 73% at 670 nm.
