DYE FOR DYE SENSITIZED SOLA CELL COMPRISING BICARBAZOLE DERIVATIVES AND SOLA CELL COMPRISING IT

摘要

PURPOSE: A dye for a dye-sensitized solar cell is provided to improve photoelectric conversion efficiency of the dye-sensitized solar cell by emitting many electrons because two carbazole compounds which perform a role of electron donor are connected. CONSTITUTION: A dye compound for a dye-sensitized solar cell is represented as below chemical formula 1. R and R' are respectively selected from hydrogen, C1-12 alkyl group, C2-12 alkenyl group, C2-12 alkynyl group, C2-12 vinyl group, substituted or non-substituted aryl group or substituted or non-substituted heterocyclic group; A1 and A2 are respectively nonexistent; or A1 and A2 are hydrogen, substituted or non-substituted C1-20 aliphatic hydrocarbon, substituted or non-substituted C1-20 aromatic hydrocarbon or the substituted or non-substituted C1-20 hetero ring. At least one of the hydrogen which is acidic and capable of hydrogen bonding; and an electron withdrawing group are included.
