Abstract

A photovoltaic device having a perovskite PV cell wherein the PV device operates, for example during start-up, initially in a bias-voltage operating mode, in which a bias voltage is applied to the perovskite PV cell of the PV device. The bias voltage or the energy needed for same can advantageously be drawn from the power electronics associated with the perovskite PV cell.
