Abstract
A method for operating a photovoltaic module in which the photovoltaic module has at least one perovskite solar cell. The method includes temporarily operating the photovoltaic module at the maximum power point by a control device connected to the photovoltaic module, wherein the drawing of electrical energy is interrupted when the irradiance of electromagnetic radiation impinging on the photovoltaic module falls below a predetermined threshold value. A photovoltaic device includes a photovoltaic module having at least one perovskite solar cell, and a control device connected to the photovoltaic module.
Claims11
A method comprising:
- operating, at least temporarily, a photovoltaic device comprising a photovoltaic module at a maximum power point by a maximum power point tracking regulation device connected to the photovoltaic module, with the photovoltaic module having at least one perovskite solar cell,
- wherein a withdrawal of electrical energy is interrupted when an irradiance of an electromagnetic radiation impinging on the photovoltaic module falls below a predetermined threshold value,
- wherein, when the irradiance falls below the predetermined threshold value, the photovoltaic module is electrically decoupled from the maximum power point tracking regulation device by a transistor, and
- wherein the predetermined threshold value is in a range of between 2 W/m2 and 20 W/m2,
- wherein, when the irradiance exceeds the predetermined threshold value, the photovoltaic module is electrically recoupled to the maximum power point tracking regulation device by the transistor.
