Disclosed is a barrier-type photovoltaic solder strip capable of reducing damp-heat (DH) attenuation, the photovoltaic solder strip comprising a photovoltaic solder strip body. A moisture barrier layer is arranged on a surface of the photovoltaic solder strip body that is not in contact with an electrode of a solar cell, and the moisture barrier layer can prevent external water and gas from entering the photovoltaic solder strip body, thus, on the basis of low cost, corrosion of the photovoltaic solder strip body by acidic substances, oxidizing agents and water in a module is reduced, thereby reducing attenuation of a photovoltaic module in a DH environment.

Embodiments may perform delamination of a photovoltaic module through the application of radiation. Radiation of one or more specific typese.g., microwave (MW); Infrared (IR); othersmay be applied to one or more faces of the PV module. By targeting polymer(s) of a laminate, radiation emitters (MW; IR; and/or other) may be energy efficient, avoiding the need to heat up the full large thermal mass of an entire laminate. By focusing upon absorption of the radiation by polymer(s), embodiments may allow for the applied radiation to be better used during the delamination process.
