Metal-organic framework (MOF) composites have garnered significant attention for their application in solar cells due to their inherently porous structures and tunable properties. MOF composites are hybrid materials formed by combining MOFs with other substances, such as polymers, nanoparticles, or biomolecules, to create materials with enhanced or tailored properties. This chapter begins with a brief summary of the synthetic methodologies employed in the preparation of MOF composites. It further examines their diverse roles, including applications as working electrodes, photocathodes, sensitizers, and electrolytes in dye-sensitized solar cells, as well as their functions as perovskite layers, interfacial layers, and electron (or hole) transport layers in perovskite solar cells. Additionally, the chapter discusses the utilization of MOF composites in organic solar cells. Finally, it addresses current challenges and outlines prospective directions for advancing MOF composite-based nanomaterials in the field of solar cell technology. © 2025 Elsevier Inc.
