← ScienceWhich outcome reduces dye-sensitized solar cell efficiency by altering electron movement between TiO2 orbitals?
A)Increased surface plasmon resonance
B)Enhanced Förster resonance energy transfer
C)Accelerated electron-hole recombination✓
D)Improved quantum confinement effects
💡 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.
