← ScienceWithin a dye-sensitized solar cell which mechanism allows the injected electron to occupy the titanium dioxide conduction band?
A)Molecular orbital hybridization✓
B)Quantum tunneling dissipation
C)Valence band electron resonance
D)Ferroelectric domain alignment
💡 Explanation
Molecular orbital hybridization allows injected electrons to share a continuous distribution of states because the dye's excited state forms a combined orbital with the TiO2. Therefore electrons enter the conduction band, rather than being trapped by localized surface states or direct recombination.
