Bi-metallic [Cu/Co(6mna)2]n metal organic chalcogenolate frameworks as high-performance electro-catalysts for dye-sensitized solar cells: a ligand-assisted bottom-up synthesis

“…; (2) pyridine-based MOFs including [Co(DAPV)] n (DAPV = di(3-diaminopropyl)-viologen). 18 On the other hand, three types of MOFs have been applied as high-performance electro-catalysts on the counter electrodes in DSSCs: 12 (1) imidazole-based MOFs including [Co(2-MeIm) 2 ] n (ZIF-67; 2-MeIm = 2-methylimidazole; ZIF = zeolitic imidazolate framework), [19][20][21][22][23][24][25][26][27][28][29][30] [Zn(2-MeIm) 2 ] n (ZIF-8), [31][32][33][34][35][36][37][38] and [Zn(PhIm) 2 ] n (ZIF-7; PhIm = benzimidazolate); 39 (2) benzene-carboxylate-based MOFs including [Co(BDC)] n , 40 [Cu 3 (BTC) 2 ] n , 41 [Zn 3 (BTC) 2 ] n , 42 [Co 3 (BTC) 2 ] n 43 and [Ni 3 (BTC) 2 ] n ; 43 (3) TCPP-based MOFs (TCPP = tetrakis(4carboxyphenyl) porphyrin) such as [(Co 3 O) 2 (TCPP) 3 ] n (PIZA-1), 44 [Zr 6 O 4 (OH) 4 )(TCPP) 3 ] n (MOF-525), 45 [(Zn 2 (COO) 4 (TCPP) 4 ] n (Zn-TCPP), 46,47 and Cu-TCPP. 48 As summarized in Table S1, † most of these MOFs were used as the precursors/templates for the synthesis of various N-doped carbonaceous materials, transition metal carbides/oxides/suldes/selenides, and their composites, via high-temperature thermal treatments.…”

Synthesis of Carbon Nanotubes Using Modified Hummers Method for Cathode Electrodes in Dye-Sensitized Solar Cell

“…Dye-Sensitized Solar Cell (DSSCs) consists of four main components, they are the anode electrode, the cathode electrode, the electrolyte, and the dye. Many researchers have resorted to increase in the efficiency either by improving the dye or by using nanomaterials, especially the carbon family (as carbon nanotubes and graphene) [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33] . Have prepared dye-sensitized solar cell utilization multiwalled carbon nanotubes(MWCNTs) as the counter electrode and titanium oxide TiO2 nanoparticles as the anode electrode with the use of an industrial dye (cis-diisothiocyanato-bis (2.2'-bipyridyl-4.4'dicarboxylic acid) ruthenium (II) knows as N3, the multi-walled carbon nanotubes (MWCNTs) are coated on the conductive glass FTO by a spin coating method, giving the cell Voc 626.23 mA, Isc 3.14 mA, Imax 2.332 mA, Vmax 381.95 mV, fill factor (FF) 0.49, conversion efficiency (E%) 1.97 18 .…”

State-of-the-art with the prospects of cobalt-based metal-organic frameworks for solar cell applications

“…Since the crystalline porous MOFs have the capacity to assemble and arrange a large number of photoactive elements in a highly organized periodic manner, these can carry out multiple tasks simultaneously, including charge transportation and conversion of light into electrical energy, among others. Due to their physiochemical tunability and ecological robustness, MOFs may now be used as an active component in solar cell devices [25][26][27][28][29].…”
