2,5-Dithienylpyrrole (DTP) as a donor component in DTP-pi-A organic sensitizers: photophysical and photovoltaic properties

Abstract

Organic dyes have been prepared to evaluate the ability of 2,5-dithienylpyrrole (DTP) to act as a donor substituent in D-pi-A sensitizers for DSSCs. Using a styryl pi-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.
