High efficient donor–acceptor ruthenium complex for dye-sensitized solar cell applications

Dye‐Sensitized Solar Cells with Improved Performance using Cone‐Calix[4]Arene Based Dyes

“…The cyclic voltammograms of dyes were obtained with a CHI 832 electrochemical analyzer using a normal three-electrode cell with dye-sensitized photoanode as working electrode, a Pt wire counter electrode, and a regular Ag/AgCl reference electrode in saturated KCl solution. CVs were measured with 0.1 m tetrabutylammonium hexafluorophosphate (TBAPF 6 ) as a supporting electrolyte in CHCl 3 and calibrated with ferrocene/ferrocenium (Fc/Fc + ) as an external reference, scan rate was kept as 50 mV s À1 for all compounds. The electrochemical impedance spectra were measured using an electrochemical workstation (Zahner, Zennium) with a frequency response analyzer at a bias potential of À800 mV in the dark with a frequency ranging from 10 mHz to 1 MHz.…”

A facile and convenient synthesis and photovoltaic characterization of novel thieno[2,3-b]indole dyes for dye-sensitized solar cells

“…A high efficiency for conversion of light into electric power of up to 11% has been obtained for DSSC, based on polypyridyl ruthenium complexes, as the dye [3]. However, applications of Ru-dyes are limited since ruthenium is a rare and a very expensive noble metal; besides that Ru-based dyes have relatively low values of molar extinction coefficients.…”

Highly efficient and stable cyclometalated ruthenium(II) complexes as sensitizers for dye-sensitized solar cells

“…One of the key components of DSSCs is the photosensitizer, which absorbs light from sun and transfers an electron from its excited state to the conduction band of TiO 2 . Various sensitizers, such as ruthenium complexes [2][3][4], non-ruthenium metal complexes [5][6][7][8], and organic sensitizers [9][10][11][12][13], have been applied in DSSCs. The most common sensitizers are Ru(II) complexes based on 4,4'-dicarboxy-2,2'-bipyridine (dcbpy) ligands, such as [Ru(dcpbpy) 2 (NCS) 2 ] (N3 [14] and N719 [15]) and their derivatives [16][17].…”
