The present invention relates to a dye-sensitized solar cell and a method for producing the dye-sensitized solar cell, and more particularly, to a dye-sensitized solar cell improved in performance using organic dyes having two or more carbazole molecules each having a strong electron donor role, . To this end, the present invention provides a light emitting device comprising a first substrate, a first electrode located on the first substrate, a semiconductor layer located on the first electrode, a dye layer located on the semiconductor layer, And a second substrate on which a second electrode and a counter electrode are sequentially disposed, and a first substrate and a second substrate which are positioned and sealed by barrier ribs, wherein the dye layer comprises a plurality of carbazole derivatives . Therefore, it is possible to improve the performance by increasing the extinction coefficient and the photoelectric conversion efficiency by using an organic dye having two or more carbazole molecules having a strong electron donor role in the solar cell. |
