Palmyrah Seed-Derived Activated Charcoal/TiO₂ Composites as a Counter Electrode for Dye-Sensitized Solar Cells.

ABSTRACT: Platinum (Pt) is a widely used counter electrode (CE) material in dye-sensitized solar cells (DSSCs) due to its excellent catalytic properties. However, the steep cost limits its widespread adoption. This has spurred researchers to focus on carbon-based materials, which are abundant and economically viable alternatives. In this study, charcoal was derived from palmyrah seeds and activated by a simple thermal shock method involving rapid water immersion. This palmyrah seed-based activated charcoal (AC) was then combined with TiO₂ to create a novel composite paste, enhancing amalgamation between carbon particles and adhesion of the carbon particles on the FTO glass substrate. XPS analysis confirmed the successful formation of the palmyrah seed-derived charcoal. Raman spectroscopic
