The dye compound of the present invention is used in a dye-sensitized solar cell (DSSC), and improves molar absorptivity, short circuit photocurrent density (Jsc) and photoelectric converting efficiency which significantly enhances the efficiency of the solar cell. The novel organic dye and preparation method therefor according to the present invention allows for refining the process without requiring an expensive column and remarkably reduces costs for dye synthesis.
