Which mechanism reduces diode reverse leakage when lightly doping extra silicon?

💡 Explanation

Light doping widens the depletion region reducing reverse leakage due to bandgap narrowing; because lowered carrier density lessens the tunneling probability. Therefore, leakage is reduced rather than worsened by increasing recombination current at the surface.
