Abstract
Embodiments of a degradation phenomenon treatment method based on a photovoltaic module and a related device are disclosed. A high frequency signal is applied to the photovoltaic module when a degradation phenomenon occurs in the photovoltaic module to protect the photovoltaic module and suppress or eliminate the degradation phenomenon. The degradation phenomenon refers to degradation of electricity generation efficiency of the photovoltaic module under effect of an electric potential. Embodiments of the degradation phenomenon treatment method and the device resolve issues associated with a declined electrical energy conversion capability and decreased electricity generation efficiency of a photovoltaic module caused by a surface polarization phenomenon, a potential induced degradation (PID) phenomenon occurring in the photovoltaic module, or both.
