Molecular Engineering of New Thienyl-Bodipy Dyes for Highly Efficient Panchromatic Sensitized Solar Cells

Stepwise construction of thienyl‐bodipy dyes bearing a carboxylic acid or an acrylate function is realized. The color of the dye is tuned by the presence of one or two vinyl‐thienyl arms. These highly colored dyes exhibit strong absorption spanning to 760 nm when anchored to TiO2 nanoparticles. The...

Zusammenfassung:Stepwise construction of thienyl‐bodipy dyes bearing a carboxylic acid or an acrylate function is realized. The color of the dye is tuned by the presence of one or two vinyl‐thienyl arms. These highly colored dyes exhibit strong absorption spanning to 760 nm when anchored to TiO2 nanoparticles. The use of two complementary absorbing dyes produces a conversion efficiency of 6.43% and a incident photon‐to‐current conversion efficiency (ICPE) plateau of about 70% between 500 and 700 nm.
