Copper(ii) and cobalt(iii) Schiff base complexes with hydroxy anchors as sensitizers in dye-sensitized solar cells (DSSCs)

Abstract

Two new imine based cobalt and copper complexes synthesized and used as sensitizers in DSSCs.

Recent Investigations on the Use of Copper Complexes as Molecular Materials for Dye-Sensitized Solar Cells

“…In the same year, Chauhan, Kumar, and coworkers published new homoleptic Cu(II) and Co(III) complexes (compounds 7 and Co-Sal , structure in Figure 6 ) having a bidentate N^O ligand obtained by the condensation of salicylaldehyde with ethanolamine [ 34 ].…”

Effect of metal ions in the electron-transfer mechanism on the photovoltaic performance of SALPHEN-based DSSC: experimental and theoretical studies

“…In particular, metal ions with incomplete valence shell configurations show intrinsic chemical characteristics when there are multi-dentate ligands in the metal complex, which has attracted considerable attention in the development of renewable energy technologies. [8][9][10][11] The incorporation of suitable metal ions with a suitable ligand usually increases the HOMO-LUMO energy gap, which allows the excited-state electron to have a longer lifetime even at high temperatures, increasing the overall luminescence quantum yield of DSSCs. 12 It is known that the efficiency of a DSSC is dependent on the photosensitizers used between the electron donor and acceptor electrodes, which should have a broad and strong light absorption capable of covering the entire visible and near-infrared regions (NIR) and be stable to a certain temperature.…”
