Simple N-Hexylcarbazole based metal free sensitizer for Dye Sensitized Solar Cells (DSSC) Application - A quantum chemical approach

N-Hexylcarbazole based Metal-free organic sensitizers have been designed for dye-sensitized solar cell applications. The designed dyes were analyzed by density functional theory and time-dependent density functional theory. The various parameters such as geometry, electronic structure, highest occupied molecular orbital and lowest unoccupied molecular orbital, light harvesting efficiency and electronic absorbance spectrum of the designed sensitizers were analyzed. The results show that the designed dyes may be an efficient sensitizer for DSSC applications.
