COMPOUNDS HAVING HOLE CONDUCTING PROPERTY, CO-ADSORBENT BODY COMPRISING SAME, AND DYE-SENSITIZED SOLAR CELL COMPRISING THE CO-ADSORBENT BODY

摘要

An object of the present invention is to provide a novel concept coadsorbent that can be used instead of conventionally-used deoxycholic acid (DCA).;The present invention provides a coadsorbent having hole conduction characteristics, including the compound represented by Formula 1, 2, 3 or 4, and provides a dye-sensitized solar cell including a light absorbing layer including the coadsorbent having hole conduction characteristics.;The photocurrent and photovoltage of the dye-sensitized solar cell can be improved because it includes a light absorbing layer including the coadsorbent having hole conduction characteristics.
