Metal complex dye for a photoelectrochemical cell

摘要

A photoelectric conversion device comprising semiconductor particles sensitized by a metal complex dye represented by the following general formula (I): (LL1)m1(X1)m2M1(BL)M2(LL2)m3(X2)m4 . CI wherein M1 and M2 independently represent a metal atom; BL represents a ligand having two or more moieties for bidentate or tridentate coordination to the metal atoms; LL1 and LL2 independently represent a bidentate or tridentate ligand with a particular structure, which coordinates to the metal atoms via nitrogen atoms; X1 and X2 independently represent a monodentate or bidentate ligand which coordinates to the metal atom via a dithiocarbamate group, a thiocyanate group, etc.; m1 and m3 independently represent 0 or 1; m2 and m4 independently represent an integer of 0 to 4; and CI represents a counter ion optionally contained to neutralize charge of said metal complex dye. A photoelectric cell comprising the photoelectric conversion device is also provided.
