A power conversion system includes an electrical generator operable to generate an electrical power and an electrical transmission system that is operable to transmit the electrical power from the electrical generator, the electrical transmission system having a maximum physical power transmission rate. A flexible load is operable in response to the receipt of the electrical power from the electrical transmission system to convert a portion of the electrical power into a form of stored energy. The electrical transmission system is separate from any grid code regulated systems, and the electrical transmission system is configured to transmit electrical power from the electrical generator to the flexible load at a rate that is 75 percent to 100 percent of the maximum physical power transmission rate.

A computer-implemented method and system provides output data, wherein the output data includes a performance value of a perovskite-based solar cell. The method includes: (i) receiving input data, wherein the input data includes data from electrical impedance spectroscopy carried out on the solar cell or parts thereof, (ii) applying a trained function to the input data, wherein the output data is generated and (iii) providing the output data. A computer-implemented method also provides a trained function which is able to predict a performance value of a perovskite-based solar cell based on electrical impedance spectroscopy carried out on the solar cell or parts thereof.

A method for control of a cooling device for the active cooling of a perovskite solar cell, wherein the perovskite solar cell is part of a perovskite photovoltaic module. The method includes determining a measure of the internal temperature of the perovskite solar cell and activating the cooling device when the determined measure of the internal temperature of the perovskite solar cell is greater than a corresponding measure of a predetermined temperature threshold value. A photovoltaic apparatus having a perovskite photovoltaic module includes at least one perovskite solar cell, and a cooling device for the active cooling of the perovskite solar cell.

Energy-efficient cooling of a perovskite solar cell

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.

A photovoltaic device includes a first group of photovoltaic cells of a first cell type, the first group of photovoltaic cells operable to produce a first current and a first voltage, and a second group of photovoltaic cells of a second cell type that is different than the first cell type, the second group of photovoltaic cells operable to produce a second current and a second voltage. A first power electronics unit is connected to the first group of photovoltaic cells, and a second power electronics unit is connected to the second group of photovoltaic cells. The second power electronics unit is separate from and not communicating with the first power electronics unit. A control device is operable to vary a first property of the first power electronics unit to vary the first current and the first voltage and to vary a second property of the second power electronics unit to vary the second voltage and the second current independent of the first voltage and the first current.
