제목 Effect of Energy Level Modification in Fullerene Acceptors on Photovoltaic Parameters and Stability
초록 Fullerene bis-adducts have great potential for enhancing the efficiency of polymer solar cells by improving Voc due to their high LUMO level. However, high LUMO levels of fullerenes inhibit the charge transfer of photo-induced excitons. Therefore, fullerene LUMO level is needed to be tuned for optimizing energy level between donor and acceptor. In this work, new fullerene derivatives containing electron withdrawing group have been synthesized to adjust LUMO energy level. We investigate the relationship between molecular structure of fullerene derivatives and their photovoltaic properties.
