“…Still, its high cost and corrosive characteristics in currently used electrolytes hinders its practical application in long-term DSSC devices [14]. Low-cost alternative candidates to Pt, such as carbonaceous materials [15][16][17][18][19], conductive polymers [20], metal sulfides [21][22][23], metal phosphides [24], metal selenides [25,26], oxides [27], and other cost-effective materials [28], have been widely investigated and have demonstrated good catalytic performance for triiodide reduction. In particular, carbonaceous materials are attractive to replace platinum due to their high electronic conductivity, good stability, high reactivity for triiodide reduction, and low cost [29].…”

In this work, carbon xerogels (CXGs) doped with nitrogen or sulfur have been investigated as DSSC counter electrodes. CXGs have been prepared by a sol–gel method from resorcinol and formaldehyde and subsequent carbonization. Nitrogen doping has been carried out by introducing melamine into the synthesis process along with resorcinol and formaldehyde, while sulfur has been incorporated by direct reaction of the carbon material with elemental sulfur. The counter electrodes for DSSCs have been prepared by airbrushing on conductive glass (fluorine-doped tin oxide, FTO), and their electrochemical behavior has been evaluated, observing that the introduction of heteroatoms such as nitrogen or sulfur leads to an improvement in efficiency compared to the undoped material thanks to a decrease in charge transfer resistance.

“…So far ZIF-67 has been the most intensively studied MOF as a template/precursor for the construction of CE for DSSCs. ZIF-67 derivatives including metallic cobalt-based composites, cobalt sulfides, cobalt-molybdenum sulfides, cobalt selenides, and cobalt tellurides have been explored as CE for DSSCs [155,[161][162][163][164][165][166][167][168][169][170][171][172][173][174][175][176][177][178][179].…”

“…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.…”

“…ZIF-67 is a common type of MOF constituted by cobalt metal linked with four nitrogen atoms (Co-N4) to tetrahedral frameworks [165]. A similar approach was employed by Liu and co-workers to obtain MoS 2 @Co 3 S 4 composites employing ZIF-67 as both template and cobalt source [95]. The composites showed promising synergistic effect on the catalysis of triiodide reduction.…”

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

Metal-organic frameworks (MOFs) and covalent organic frameworks (COFs) are two innovative classes of porous coordination polymers. MOFs are three-dimensional materials made up of secondary building blocks comprised of metal ions/clusters and organic ligands whereas COFs are 2D or 3D highly porous organic solids made up by light elements (i.e., H, B, C, N, O). Both MOFs and COFs, being highly conjugated scaffolds, are very promising as photoactive materials for applications in photocatalysis and artificial photosynthesis because of their tunable electronic properties, high surface area, remarkable light and thermal stability, easy and relative low-cost synthesis, and structural versatility. These properties make them perfectly suitable for photovoltaic application: throughout this review, we summarize recent advances in the employment of both MOFs and COFs in emerging photovoltaics, namely dye-sensitized solar cells (DSSCs) organic photovoltaic (OPV) and perovskite solar cells (PSCs). MOFs are successfully implemented in DSSCs as photoanodic material or solid-state sensitizers and in PSCs mainly as hole or electron transporting materials. An innovative paradigm, in which the porous conductive polymer acts as standing-alone sensitized photoanode, is exploited too. Conversely, COFs are mostly implemented as photoactive material or as hole transporting material in PSCs.
