Compounds with hole conducting property, their use as co-adsorbent materials, and dye-sensitized solar cell comprising the same

摘要

PURPOSE: A compound with hole conduction and a solar cell comprising the same are provided to enhance further form electric potential difference from Fermi level. CONSTITUTION: A compound with hole conduction is denoted by chemical formula 1 or 2. A coadsorption body with the hole conduction contains the compound of chemical formula 1 or 2. A dye-sensitized solar cell contains an optical absorption layer containing the coadsorption body. The dye-sensitized solar cell comprises a first electrode having a conductive transparent substrate, the optical absorption layer formed at one side of the first electrode; a second electrode placed to face the first electrode; and a electrolyte between the first and second electrodes.
