← ScienceWhich outcome occurs when misaligned molecular orbitals in organic LEDs encounter a potential barrier?
A)Lower forward voltage results immediately
B)Polaron formation causes device degradation✓
C)Increased electroluminescence happens rapidly
D)Exciton formation dominates spontaneously always
💡 Explanation
Polaron formation causes device degradation, because *hopping conduction* requires electrons overcome energy barriers for charge transport therefore creating charged polarons from trapping, rather than improved efficiency or immediate effects observable at lower voltage.
