Which outcome reduces photodiode efficiency when photons strike?

💡 Explanation

Electron-hole recombination reduces generated carriers, because defects introduce energy levels within the bandgap, facilitating the Shockley–Read–Hall mechanism. Therefore, fewer carriers contribute to the photocurrent, rather than increased dark current from thermal effects or enhanced collection.
