The invention discloses a packaging method of a photovoltaic module. The method is used for sealing a battery piece and includes the following steps: stacking, namely tempered glass, a first bonding piece, the battery piece, a second bonding piece and rear panel glass are sequentially stacked from the bottom to the top to form a stacked piece, and the first bonding piece and the second bonding piece are both solid silica membranes; laminating, namely arranging the stacked piece in a laminating machine, vacuumizing and heating, bonding the tempered glass, the first bonding piece, the battery piece, the second bonding piece and the rear panel glass to form a laminated piece, cooling, and taking the laminated piece out; and framing the laminated piece to obtain the photovoltaic module. By means of an embodiment of the packaging method, the photoelectric property, weather fastness and reliability of the photovoltaic module can be improved, the service life of the module is prolonged, the module cost is reduced, and packaging process is optimized. In addition, the invention further discloses the photovoltaic module packaged through the packaging method.
