Abstract

Three new 2DepeA dyes (TK4, TK5 and TK6), composed of diarylamine donor groups, a dibenzofulvenethiophenecore as the p-bridge, and a cyanoacrylic acid anchoring group as the acceptor, have beensuccessfully designed, synthesized, and characterized both experimentally and computationally. Theperformance in DSSC solar cells has been also studied. Octyloxy chains were introduced on the backboneof the dye, in order to increase donor capability, avoid aggregation side effects and increase physicalinsulation between electrolyte system and the TiO2 layer. The dye containing the octyloxy chains on thedonor group and two thiophene ring as an extension of p-bridge showed the best photovoltaic performancewith a maximum of solar energy-to-electricity conversion yield of 7.8% under AM 1.5 irradiation(100 mW/cm2).
