Which consequence results when quantum tunneling fails in photovoltaic cells?

💡 Explanation

Reduced current generation efficiency occurs because electron transport across the band gap becomes less efficient via quantum tunneling. This is because tunneling is improbable when barriers are wider, therefore cells become less efficient at converting photons, rather than generating heat, which also reduces it.
