Abstract
Metal-organic frameworks (MOFs) and MOF-derived materials have been used for several applications, such as hydrogen storage and separation, catalysis, and drug delivery, owing to them having a significantly large surface area and open pore structure. In recent years, MOFs have also been applied to thin-film solar cells, and attractive results have been obtained. In perovskite solar cells (PSCs), the MOF materials are used in the form of an additive for electron and hole transport layers, interlayer, and hybrid perovskite/MOF. MOFs have the potential to be used as a material for obtaining PSCs with high efficiency and stability. In this study, we briefly explain the synthesis of MOFs and the performance of organic and dye-sensitized solar cells with MOFs. Furthermore, we provide a detailed overview on the performance of the most recently reported PSCs using MOFs.
Highlights
Increasing the absorbance two times, increasing the hole mobility, and reducing the grain size led to improved power conversion efficiency (PCE). These results demonstrate the potential of tunable 2D metal-organic frameworks (MOFs) nanosheets as materials to improve the performance of a wide range of Organic solar cells (OSCs)
Dye-sensitized solar cells (DSSCs) are cost-effective because they are manufactured with inexpensive materials and have simple manufacturing processes
The porous structure and large surface area resulting from enhance the performance of DSSCs by augmenting the transport of interfacial carriers, dye adsorption, the introduction of the MOFs is believed to enhance the performance of DSSCs by augmenting the and light harvesting
Summary
Porous materials are widely used in various fields owing to their large specific surface area and easy and fast diffusion of ions and electrons through the pores. MOF is a porous, organic–inorganic hybrid compound, wherein a metal ion and an organic ligand are connected by coordination to form a three-dimensional structure (Figure 1). Because MOFs have a significantly large surface area and open pore structure, they can transport larger amounts of molecules or solvents compared to other porous materials. Another advantage of MOFs is their ability to modify the composition of the metal-organic ligands, thereby showing various properties and controlling the size of pores. Recent studies on the application of MOFs to perovskite solar cells (PSCs), which are highlighted as next-generation solar cells that may replace silicon solar cells, are2summarized
