1. A barrier-type photovoltaic solder strip for a photovoltaic module comprising at least one solar cell, wherein the barrier-type photovoltaic solder strip is capable of reducing damp-heat (DH) attenuation and comprises a photovoltaic solder strip body and a moisture barrier layer provided on a surface of the photovoltaic solder strip body that is not to be in contact with an electrode of the at least one solar cell,
wherein a material of the moisture barrier layer comprises tetrafluoroethylene-hexafluoropropylene-vinylidene fluoride copolymer (THV) with a mass percentage in a range of 20% to 55%, polyvinylidene fluoride (PVDF) with a mass percentage in a range of 10% to 45%, polyvinyl fluoride (PVF) with a mass percentage in a range of 20% to 35%, and ethylene-chlorotrifluoroethylene copolymer (ECTFE) with a mass percentage in a range of 10% to 30%.
