제목 Synthesis of Strong Electron-Withdrawing Fluorine and Trifluoromethyl Substituted Conjugated Polymers for Photovoltaic Applications
초록 Three conjugated polymers (PTBDT-Qx, PTBDT-QxCF3, and PTBDT-FQxCF3) consisting of quinoxaline (Qx) as electron acceptor and 4,5-dioctylthiophen-2-yl modified benzodithiophene (BDT) as electron donor have successfully been synthesized. Different substitutions of strong electron-withdrawing moieties (fluorine atoms and trifluoromethyl groups) into multi-positions in the Qx backbone and side chains were done for each polymer. This study clearly shows an improvement in the photovoltaic device performance along with the increasing number of strong electron-withdrawing groups in the structures. As a result, an enhancement of power conversion efficiency (PCE) up to 6.47% has successfully been accomplished.
