<p>The first metal complex dye comprising a metal atom, bidentate or tridentate ligand(s) having nitrogen atoms, and monodentate or bidentate ligand(s) which coordinates to the metal atom via an acyloxy group, a 1,3-diketo group, etc. has a high stability to heat and light, and can efficiently sensitize semiconductor particles. The first photoelectric conversion device comprising the first dye exhibits a high stability to heat and light, and an excellent photoelectric conversion efficiency. The second metal complex dye comprising a metal atom, bidentate ligand(s) with a particular structure, and optional bidentate or tridentate ligand(s) having nitrogen atoms and a monodentate or bidentate ligand(s) such as 1,3-diketones, etc. has a high absorbancy at a large wave range, and can efficiently sensitize semiconductor particles. The second photoelectric conversion device comprising the second dye exhibits an excellent photoelectric conversion efficiency. These photoelectric conversion devices are useful for a photo-electrochemical cell. <IMAGE></p> |
