The efficiency of light emitters is limited by loss mechanisms that are experimentally difficult to probe. I will discuss the theoretical advances that are enabling us to quantitatively evaluate the rate of nonradiative processes such as Auger recombination and defect-assisted carrier recombination. Our approach allows us to suggest specific strategies for increasing the efficiency of nitride or halide perovskite light emitters, and is also applicable to quantum emitters.
