Which outcome limits electron flow as crystal lattice defects approach the exciton binding energy in an organic LED?

💡 Explanation

Increased non-radiative electron-hole recombination is the correct outcome. A higher defect density increases trap states in the band gap, prompting Shockley-Read-Hall recombination. Therefore, excitons decay without light emission, rather than radiative recombination that creates photons.
