Metal–organic framework-derived cobalt diselenide as an efficient electrocatalyst for dye-sensitized solar cells

Emerging applications of metal-organic frameworks and derivatives in solar cells: Recent advances and challenges

“…Rather than using ZIF-8 for the synthesis of carbon materials, Wang et al instead sulfurized ZIF-8 to obtain ZnS micropolyhedrons [189], which showed excellent performance as CE in DSSCs for electrocatalytic reduction of I -/I 3 due to the ZIF-8 skeleton. 2 ) [190], Co-MOF [191], Ni-MOF (NiBDC) [192], ZIF-7 [193],…”

Metal Chalcogenides (MxEy; E = S, Se, and Te) as Counter Electrodes for Dye–Sensitized Solar Cells: An Overview and Guidelines

“…[184][185][186][187][188][189][190][191] However, very few research works report their use as CEs in DSSCs. [192][193][194][195][196][197][198] In these reports, most MOF-based metal chalcogenide CEs were prepared via in situ calcination and selenization. [192,193,196,197] Hsu et al [197] were the first to synthesize an MOF-derived chalcogenide in 2014 for use as a CE for a DSSC.…”

“…Their detailed work quickly promoted the synthesis of MOF-derived chalcogenide based CEs for DSSCs. In the same year, Wang et al [192] [195] synthesized and compared two MOFderived selenides obtained using in situ selenization in a quartz tube oven (CoSe 2 -D) for the first and using hydrothermal selenization (CoSe 2 -S) for the other. They found that the structure of CoSe 2 -S showed excellent electrocatalytic activity similar to a Pt CE, with porous nanoparticles, beneficial for the diffusion ability of the I À /I 3 À redox couple, and superior to the CoSe 2 -D CE.…”

Application of Metal-Organic Frameworks and Covalent Organic Frameworks as (Photo)Active Material in Hybrid Photovoltaic Technologies

“…Indeed, they could be employed as sensitizer materials [86][87][88][89], electrolyte additives [90] or electrode materials [91][92][93]. In some cases, they have been employed as templates to obtain materials with tailored properties [94][95][96][97]. Hereafter, we report on the different approaches that have been exploited in literature.…”

“…It is worth mentioning that this work opens the doors to the use of selenium-based materials in place of the more exploited sulphur-based counterparts (Figure 8). More recently, Wu et al reported CoSe 2 -D as effective MOF-derived CEs [96]. They synthesized the MOF precursor directly on FTO glass via electrodeposition followed by a solvothermal process and then in-situ selenized.…”
