Dr. Omar Britel is a dynamic researcher at the Department of Chemistry, Faculty of Sciences Dhar El Mahraz, Sidi Mohamed Ben Abdellah University in Fez, Morocco. His work revolves around the intriguing world of dye-sensitized solar cells (DSSCs) and the profound impact of electron acceptors on the photovoltaic properties of organic dyes. Dr. Britel's research focuses on a novel series of organic dyes known as Mi (i= 2-10), derived from M1. Through the innovative use of Density Functional Theory (DFT) and Time-Dependent Density Functional Theory (TDDFT) methods, he delves deep into the molecular world to uncover the influence of various internal acceptor groups on the efficacy of these dyes in DSSCs.
