Organic dyes have been prepared to evaluate the ability of 2,5-dithienylpyrrole (DTP) to act as a donor substituent in D–π–A sensitizers for DSSCs. Using a styryl π-bridge the dyes were found to be excellent sunlight harvesters when adsorbed on TiO₂ photoanodes with absorbances >3 in the 300–550 nm region. Calculations as well as transient absorption spectroscopy in both solution and on a TiO₂ surface revealed that they were favourable for efficient injection and regeneration.
