Organic dyes are provided to improve molar absorptivity, short circuit photocurrent density (Jsc) and photoelectric converting efficiency, thereby significantly enhancing the efficiency of a solar cell, to allow for refining the process without requiring an expensive column and to remarkably reduce costs for dye synthesis. Acridine-based dye has a structure represented by chemical formula 1. In chemical formula 1, R1 is C1~C20 alkyl group, C6~C30 aryl group, heteroaryl group or acyl group; R2, R3, R4, R5, R6, R7, R8 and R9 are independently hydrogen, C1~C10 alkyl group, halide group, C1~C10 alkoxy group, acyl group, C6~C30 aryl or heteroaryl group; Ar is a compound including at least one kind of a compound having heteroatom of C6~C30 aryl group, C4~C30 heteroaryl group or aryl amino group; Y is hydrogen, C1~C20 alkyl group, C1~C20 alkoxy group, halogen atom, amide group, cyano group, hydroxyl group, nitro group or acyl group; m" is an integer of 1-4; and n is an integer of 1-7.
