Abstract

AZO dyes have been recognized as a significant class of organic dyes for optoelectronic applications due to their unique properties. As a result, a dye with a chemical structure including nitrile group as acceptor, [sbnd]N[dbnd6]N[sbnd] as π-conjugation spacers, and dimethylaniline as donor has been synthesized. Herein, the performance of an AZO-based dye compound with a power conversion performance of 0.47% is examined in DSSCs for the first time. The Density Functional Theory and Time Dependent Density Functional Theory are employed to analyze the electronic and photovoltaic properties of the dye. It is believed that this work will ease up in understanding the AZO-based dyes utilized for DSSCs.
