Which defect hinders solar cell efficiency due to Shockley-Read-Hall recombination?

💡 Explanation

Increased mid-gap states provide energy levels in the band gap, enhancing Shockley-Read-Hall recombination, because electrons and holes get trapped and recombine. Therefore carrier lifetime decreases and efficiency is reduced, rather than enhancing plasmons affecting surface effects.
