Abstract
In recent years, dye-sensitized solar cells (DSSC) have been studied using various transition metals such as ruthenium, osmium, and platinum as sensitizers. However, these transition-metal dye molecules often require complicated synthetic pathways that can be quite expensive. As a result, this study focuses on using nickel as an alternate inexpensive transition metal with a simpler synthetic pathway. In particular, the study will use nickel diimine complexes as sensitizers for the formation of DSSC. This investigation will include determining the best synthetic route of nickel diimine complexes, Ni(3,3’-dcbpy)qdt, Ni(4,4’-dcbpy)qdt, and Ni(5,5’-dcbpy)qdt where dcbpy = dicarboxy-2,2’-bipyridine (with different steric conformations on the nickel diimine ligands) and qdt = quinoxaline-2,3-dithiolate, and maximizing their corresponding efficiencies. New compounds were experimented in place of the quinoxaline-2,3-dithiol (qdt) to enhance the readings of the solar cell and the preservation of the conductive dye.
