Above-Bandgap Photovoltages in Antiferroelectrics

Above-Bandgap Photovoltages in Antiferroelectrics

The first antiferroelectric solar cell is presented. This study shows that antiferroelectric thin‐film photovoltaic current can be switched on when biased into the polar phase to generate abovebandgap photovoltages in excess of 100 V and photovoltaic fields of several megavolts per centimeter, the l...

Zusammenfassung:The first antiferroelectric solar cell is presented. This study shows that antiferroelectric thin‐film photovoltaic current can be switched on when biased into the polar phase to generate abovebandgap photovoltages in excess of 100 V and photovoltaic fields of several megavolts per centimeter, the largest ever measured for any material.
