Which efficiency loss occurs in high-power LEDs due to increased non-radiative recombination?

💡 Explanation

Efficiency droop occurs because higher carrier densities in the active region enhance Auger recombination, a non-radiative process, dramatically reducing the LED's internal quantum efficiency. Therefore, light output diminishes at high drive currents, rather than thermal runaway or breakdown at low currents.
