Discussed is a tandem solar cell manufacturing method including etching a crystalline silicon substrate, whereby a solar cell can be obtained which does not have a pyramid-shaped defect on a surface of the substrate, inhibits the generation of a shunt through the substrate having excellent surface roughness properties, and can secure fill factor properties, the solar cell being capable of being obtained through the tandem solar cell manufacturing method. The method includes preparing a crystalline silicon substrate; performing an isotropic etching process of the substrate; and removing a saw damage on a surface of the substrate by performing an anisotropic etching process of the isotropically etched substrate.

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.
