Which mechanism limits the efficiency of silicon-based solar cells with ideal contact formation?

💡 Explanation

When solar cells are heavily doped, Auger recombination occurs because three carriers interact, promoting one electron to a higher energy level while another loses energy, thus limiting efficiency via non-radiative recombination. Therefore Auger recombination limits efficiency, rather than mismatch, bonds or tunneling, which require different material and structure defects.
