For access to the full text item, kindly consult the publisher's website.The formation, characterization, and dye sensitized solar cell application of nickel(II), zinc(II) and cadmium(II) ferrocenyl dithiophosphonate complexes were investigated. The multidentate monoanionic ligand [S2PFc(OH)]- (L1) was synthesized. The reaction between metal salt precursors and L1 produced Ni(II) complexes of the type [Ni{S2P(Fc)(OH)}2] (1) (molar ratio 1:2), and a tetranickel(II) complex of the type [Ni2{S2OP(Fc)}2]2 (2) (molar ratio (1:1). It also produced a Zn(II) complex [Zn{S2P(Fc)(OH)}2]2 (3), and a Cd(II) complex [Cd{S2P(Fc)(OH)}2]2 (4). Complexes 1–4 were characterized by 1H and 31P NMR, FTIR and elemental analysis, and complexes 1 and 2 were additionally analyzed by X-ray crystallography. The first examples of dye-sensitized solar cells (DSSCs) co-sensitized with ferrocenyl dithiophosphonate complexes 1–4 are reported. Co-sensitization with the ruthenium dye N719, produced the dye materials (3)-N719 ( =8.30%) and (4)-N719 ( =7.78%), and they were found to have a better overall conversion efficiency than the pure Ru N719 dye standard ( =7.14%) under the same experimental conditions. The DSSCs were characterized using UV/vis, cyclic voltammetry, electrochemical impedance spectroscopy (EIS), photovoltaic- (I-V curves), and performing incident photon-to-current efficiency (IPCE) measurements.enCrystal structuresDye-sensitized solar cellsDSSCElectrical impedance spectroscopyFerrocenyl-dithiophosphonatesGroup 12 elementsArticleAjayi, T., Ollengo, M., Le Roux, L., Pillay, M., Staples, R., Biros, S., ...
