Efficient electrolyte of N,N′-bis(salicylidene)ethylenediamine zinc(ii) iodide in dye-sensitized solar cells

Abstract

N,N 0 -Bis(salicylidene)ethylenediamine zinc(II) iodide (ZnLI 2 ) was synthesized and characterized by elemental analysis, UV-Vis and IR spectroscopies. This new Schiff base complex was, for the first time, applied as the electrolyte of a dye-sensitized solar cell. ZnLI 2 has high reductive activity and conductivity, resulting in larger IPCE and photoelectric conversion efficiency in the DSSCs. The best results were obtained in the optimized composite electrolyte E2, with a photoelectric conversion efficiency of 7.75% under 100 mW cm À2 irradiation. This work provides a new approach for the improvement of the photoelectrochemical properties of dye-sensitized solar cells.

Main chain polymeric metal complexes based on linkage fluorenevinylene or phenylenevinylene with thienyl(8‐hydro xyquinoline)–cadmium (II) complexes as dye sensitizer for dye‐sensitized solar cells

“…The shorter wavelength band of complex Cd(B8QTH) 2 is 4 nm red‐shifted form 365 to 369 nm. The red‐shifted mainly results from the co‐ordination of ligand with Cd(II), which weakens the conjugation plane of the complex and lowers the energy of the π* orbital of the ligand, making the ππ* transition occurs at lower energy 59. All absorption spectra of the three polymers exhibit two peaks and a shoulder above 450 nm.…”

“…Nielson et al [13] described the preparation of polymeric {TiO(N,N'-bis(salicylidene)ethylenediamine)} n from [Ti(OCHMe 2 ) 2 (acac) 2 ] and salen-H 2 in methanol solution. Yang et al [14] synthesized and characterized N,N-bis(salicylidene)ethylenediamine zinc(II) iodide (ZnLI 2 ), and applied it as the electrolyte of a dye-sensitized solar cell. Huerta-Jose et al [15] prepared and employed indium(III) complex of salen as a chemo-sensor for the recognition of HSO 4…”

Structural and spectroscopic characterization of a new luminescent NiII complex: bis{2,4-dichloro-6-[(2-hydroxypropyl)iminomethyl]phenolato-κ3 O,N,O′}nickel(II)

“…During the last decade, transition-metal complexes have been of great interest since they have potential applications in coordination chemistry, catalysis and sensors, and display biological and magnetic properties (Sherino et al, 2018;Bang et al, 2016;Vittaya et al, 2017;Hajikhanmirzaei et al, 2015;Vamja & Surati, 2017;Keypour et al, 2017). Recently, Schiff base ligands and their metal complexes have attracted attention as organic photovoltaic materials since their use as potential substitutes for dye-sensitized solar cells (DSSCs) (Zhang et al, 2018;Yang et al, 2010;Wesley Jeevadason et al, 2014;Dinçalp et al, 2010). In addition, impressive progress has been made in the photophysical and optoelectronic applications of these complexes, because they exhibit photoluminescence (PL), as well as electroluminescence (EL), and these qualities point to potential applications in the development of energy-efficient low-cost full-colour and flat-panel OLED (organic light-emitting diode) displays (Nishal et al, 2014(Nishal et al, , 2015Taghi Sharbati et al, 2011;Yan et al, 2018;Bizzarri et al, 2017).…”
