Title
Hybridized ruthenium(II) complexes with high molar extinction coefficient unit: Effect of energy band and adsorption on photovoltatic performances
Abstract

Two hybridized Ru(II) complexes cis-Ru(dcbpy)2(PNI-phen)(NCS)2 and cis-Ru(dcbpy)2(PERY-phen)(NCS)2, coded as RuPBS and RuPPS containing naphthalimide or perylene imide unit, were synthesized and utilized in dye-sensitized TiO2 solar cells (DSCs). Their absorption spectra, electrochemical and photovoltatic properties were studied. Both complexes, especially for RuPPS, have wide absorption bands with high molar extinction coefficient in the visible spectrum region. The effects of the energy band of the incorporated ligand and adsorption on TiO2 were extensively discussed. The complexes are served to enhance our knowledge regarding manipulation of new sensitizers for DSCs, providing a powerful strategy for prediction of photovoltatic performances.
