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

摘要

The aim of the present invention is to provide a novel concept co-adsorbent body which can be used in place of conventionally used deoxycholic acid (DCA). To this end, the present invention provides a compound having a hole conducting property, expressed by chemical formula 1, chemical formula 2, chemical formula 3 or chemical formula 4, a co-adsorbent body having a hole conducting property, comprising said compound, and a dye-sensitized solar cell comprising the co-adsorbent body having a hole conducting property in the light-absorbing layer thereof. According to the present invention, the dye-sensitized solar cell is provided in which the co-adsorbent body having a hole conducting property is contained in the light-absorbing layer, to thereby achieve improved photocurrent and photovoltage.
