Which outcome reduces dye-sensitized solar cell efficiency by altering electron movement between TiO2 orbitals?

💡 Explanation

Accelerated electron-hole recombination diminishes efficiency because the mechanism *non-radiative decay* within the involved TiO2 orbitals causes direct electron transitions back to the oxidized dye. Therefore, generated electrons cannot reach the external circuit, rather than contributing to power generation.
