My name is Holly Denig and I am a second year student at Florida State University. As an Environmental Engineering major, and member of the Society of Women Engineers, I have developed a passion for innovation. I am excited to apply this passion to research that helps to improve electrical conductivity, with consciousness to environmental conservation.

Improving the Efficacy of Dye- Sensitized Solar Cells with the use of Organic Dyes

Abstract

Due to advancements in technology over the past three decades coupled with the increasing demand for sustainable energy practices, more types of solar cells have been constructed and utilized in recent years. One example of these solar cells is the Dye-sensitized Solar cells (DSSCs), which utilize organic dyes for greater photon absorption. The organic composition of dyes within the dye-sensitized solar cells is less efficient than synthetic solar cells, however, they are cheaper and easier to construct on a small scale. Different dyes used can influence the efficiency of DSSCs because their chemical structures differ (carbazole, coumarin, cyanine, and hemicyanine). Therefore, the purpose of this study is to investigate the efficacy of different organic substances on photon absorption within DSSCs. We hypothesize that the best-performing organic substance will be the juice of raspberries because they contain the chemical anthocyanin which has been shown to increase photon absorption in past studies. We will also be testing dyes with chlorophyll and beta-carotene to make a comparison between the three chemical compositions. If this hypothesis holds, more DSSCs will be constructed with anthocyanin to increase energy conversion efficiency.
