1. A photovoltaic (PV) device comprising:
a perovskite PV cell for converting light impinging on the perovskite PV cell into an electrical output voltage U1, and
an arrangement for ascertaining a gauge for an internal temperature of the perovskite PV cell,
wherein the arrangement is designed, at least in a measuring state of the PV device, to measure an electrical parameter PARAM(t1) of the perovskite PV cell and to ascertain the gauge for the instantaneous internal temperature T(t1) of the perovskite PV cell from the measured parameter PARAM(t1),
wherein the electrical parameter PARAM is a cyclovoltammogram ascertainable with the aid of the method of cyclovoltammetry,
wherein the measured cyclovoltammogram CYCL(t1) represents the gauge for the instantaneous internal temperature T(t1) that is to be ascertained.
