A double co-sensitization strategy using heteroleptic transition metal ferrocenyl dithiocarbamate phenanthrolene-dione for enhancing the performance of N719-based DSSCs

Abstract

Three new ferrocene appended heteroleptic dithiocarbamate complexes have been synthesized and used as sensitizers/co-sensitizers in DSSCs.

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

“…Another example of cosensitization of solar cells is represented by the work published in the same year by Chauhan and Kumar [ 28 ]; here the copper(II) center was bound to a neutral 1,10-phenanthroline-5,6-dione and to a ferrocene-bearing dithiocarbamate ( 2 ). Moreover, the analogous nickel(II) ( Ni-Fc ) and cobalt(III) ( Co-Fc ) complexes were synthesized; the Co(III) compound had an octahedral coordination and presented one phenanthroline and two dithiocarbamate-based ligands.…”

Insights into the supramolecular and molecular electrocatalytic properties of 1,2-bis(diphenylphosphine)ethane appended nickel(ii) 1,2-dithiosquarate for oxygen and hydrogen evolution reactions

“…During the past few decades, transition metal dithiolate complexes have gained substantial attention due to their versatile applications as conducting, optical materials, and as single source precursors for binary and ternary metal sulfides and photovoltaics. 1–7 The dithiolates may be of 1,1-type, amongst which the pertinent examples are mononegative dithiocarbamates, xanthates, dithiophosphates and dithiophosphonates. 1–7 Also, 1,1-dithiolates may be dinegative, generated by reacting active methylene group-containing organic compounds with a suitable base and carbon disulfide.…”

“…1–10 The current surge in interest in dithiolate chemistry can be attributed to the functionalization of the dithiolate ligand framework, which can result in intriguing supramolecular structures in the crystalline form with altered physical characteristics. 1–8 Furthermore, crystal engineering of metal guided self-assembly of coordination complexes enabled by S⋯H, O⋯H, N⋯H, S⋯S and C⋯H (chelate, CS 2 M) non-covalent interactions plays a key role in supramolecular network organisation. 1–10…”
