Which mechanism causes photocurrent reduction in non-ideal solar cells?

💡 Explanation

Surface passivation defects cause the photoelectric response drop due to surface state recombination. The Shockley-Read-Hall recombination increases, because it produces excess trapped charges at the surface; therefore, photocurrent diminishes rather than merely changing bulk material resistivity.
