Enhancing the stability and efficiency of eye-sensitized solar cells with MIL-125 metal-organic framework as an electrolyte additive.

ABSTRACT: This study investigates how to improve the stability of liquid electrolyte (LE) dye-sensitized solar cells (DSSCs) by incorporating a titanium-based metal-organic framework (MIL-125). MIL-125, created through the coordination of Ti⁴⁺ ions with benzene-1,4-dicarboxylic acid, forms a structure that can effectively accommodate I^-/I₃^- electrolytes, resulting in a MIL-125@electrolyte assembly. This innovative assembly successfully prevents electrolyte leakage while preserving the LE properties. The study examines how the MIL-125@electrolyte enhances both stability and power conversion efficiency (PCE) of DSSCs. The inclusion of the large-surface-area of MIL-125 improves ionic conductivity, reduces charge transfer resistance, and stops leakage. The opt
