Abstract

A photovoltaic device having a perovskite PV cell having reduced aging. The internal temperature of the perovskite PV cell, or a measure thereof, is determined using a measurement of an electrical parameter. In the case that it is detected that the corresponding measured value exceeds a threshold value, i.e., that the internal temperature is too high, the operating conditions of the perovskite PV cell are adjusted to the effect that the internal temperature reduces again. This can be achieved, for example, by an input resistance of power electronics of the perovskite PV cell being adjusted such that lower ohmic losses occur, as a result of the correspondingly altered electric currents.
