← ScienceWhich mechanism inhibits electron excitation to antibonding orbitals in perovskite solar cells?
A)Increased Auger recombination losses
B)Efficient charge carrier extraction✓
C)Enhanced surface defect passivation
D)Deep trap-state electron tunneling
💡 Explanation
Efficient charge carrier extraction reduces electron density in the perovskite, enhancing the Burstein-Moss effect. This increases the bandgap because electrons fill lower energy states, therefore preventing excitation to antibonding orbitals, rather than recombination/trapping altering orbital energies.
