| Research Abstract |
Dye-sensitized solar cells (DSSC) have been regarded as next generation solar cells. In order to increase energy conversion efficiency of DSSC, I chose a 7-membered ring structure to introduce into the new sensitizing dyes, because it is expected to enhance electron injection from excited sensitizing dye to TiO2 layer. The tropolone sensitizing dye having a 7-membered ring structure was compared to benzoic acid derivative having a six-membered ring structure that is its structural isomer.
