Abstract:
The present invention relates to a dye-sensitized solar cell and a method for manufacturing the same, for providing a sensitized-solar cell which uses an organic dye with two or more connected carbazole molecules having a role of a strong electron donor to improve performance, and a method for manufacturing the same. For this, the dye-sensitized solar cell in the present invention comprises a first substrate; a first electrode located on the first electrode; a semiconductor layer located on the first electrode; a dye layer located on the semiconductor layer; and a second substrate located on the first substrate, and including a second electrode and an opposite electrode located in order, wherein the first substrate and the second substrate face each other and are sealed by a partition, and the dye layer includes multiple carbazole derivatives. Therefore, an organic dye with two or more connected carbazole molecules having a role of a strong electron donor is used in the solar cell to increase an extinction coefficient and photoelectric conversion efficiency to improve performance.

Abstract:
The present invention relates to a novel organic dye for a dye-sensitized solar cell and a dye-sensitized solar cell comprising the same, and more specifically, an organic dye with improved photoelectric transformation efficiency and a dye-sensitized solar cell comprising the same. The present invention induces an electron donor which increases a substituent and electron donor level for preventing recombination with an electrolyte in a molecule, thereby preventing open voltage drop. Also, the present invention regulates flow direction of electrons, thereby maximizing photoelectric transformation efficiency.
