Which outcome reduces solar cell efficiency due to excited electrons?

💡 Explanation

Surface electron-hole recombination causes energy loss because surface defects introduce energy states within the band gap creating more opportunities for electrons and holes to recombine non-radiatively. This reduces overall efficiency, rather than efficient operation; therefore, electron-hole recombination amplifies these losses.
