Pi-electron conjugated system the extended dye-sensitized solar cell sensitizing dye

摘要

The semiconductor particulate which sensitization is done was used with the pigment, being cheap, it designates the development of the photoelectricity sensing element whose conversion efficiency is good and the solar array which uses that as topic. Is displayed with formula (1) making the metal complex pigment or that salt which the thin film of the oxide semiconductor particulate support which is provided on the baseplate, the photoelectric sensing element which becomes.(Formula (1) in, ring a and b, c and d 1 or 3 characteristics has been allowed to have done the respective substituent. m displays the integer of 1 or 2. Z is displayed with formula (2) or (3).In formula (2) A₁ and A_{2 the} hydrogen atom, displays the aliphatic hydrocarbon residue or the arukokishiru basis which is possible to have possessed the substituent. A₃ displays the aliphatic hydrocarbon residue which is possible to have possessed the hydrogen atom or the substituent. In formula (3) A₄ and A_{5 the} hydrogen atom, displays the aliphatic hydrocarbon residue or the arukokishiru basis which is possible to have possessed the substituent. A₆ displays the aliphatic hydrocarbon residue which is possible to have possessed the hydrogen atom or the substituent.)
