Bandgap tuning of multiferroic oxide solar cells

Bandgap tuning of multiferroic oxide solar cells

Multiferroic films are increasingly being studied for applications in solar energy conversion because of their efficient ferroelectric polarization-driven carrier separation and above-bandgap generated photovoltages, which in principle can lead to energy conversion efficiencies beyond the maximum va...

Zusammenfassung:Multiferroic films are increasingly being studied for applications in solar energy conversion because of their efficient ferroelectric polarization-driven carrier separation and above-bandgap generated photovoltages, which in principle can lead to energy conversion efficiencies beyond the maximum value (∼34%) reported in traditional silicon-based bipolar heterojunction solar cells. However, the efficiency reported so far is still too low (
