Claim 0:
1. A photovoltaic module, comprising:
a substrate,
at least one solar cell string and an integrally formed packaging portion,
wherein a packaging slot is formed within a bottom side surface of the packaging portion, in a direction from bottom to top of the photovoltaic module, the substrate and the at least one solar cell string are sequentially received in the packaging slot, and a bottom side surface of the substrate is flush with the bottom side surface of the packaging portion, the at least one solar cell string is arranged on a top surface of the substrate,
a packaging gap is formed between a side surface of the substrate and an inner side surface of the packaging slot, a second packaging layer and a first packaging layer are sequentially arranged in the packaging gap in the direction from bottom to top of the photovoltaic module, the first packaging layer and the second packaging layer are configured to seal the packaging gap,
the second packaging layer is closer to an opening side of the packaging slot than the first packaging layer, the opening side is located at the bottom of the packaging portion and is recessed towards the direction from bottom to top of the photovoltaic module and opening towards the bottom side surface of the packaging portion,
wherein the packaging gap includes a first gap section and a second gap section communicated to each other along a direction from top to bottom of the substrate, the first packaging layer is configured to fill up and seal the first gap section, the second packaging layer is configured to fill up and seal the second gap section, and a side surface of the first gap section is further away from the substrate than a side surface of the second gap section,
wherein the bottom side surface of the packaging portion is away from sunlight illumination than a top side surface of the packaging portion.
