Which phenomenon causes the observed power loss in silicon-based solar cells?

💡 Explanation

Indirect band gap transitions require phonon assistance, therefore reducing radiative recombination efficiency, because silicon absorbs energy poorly in comparison to direct bandgap materials rather than Auger recombination affecting carrier density.
