Embodiment 1

[0055] After the release agent is applied to the mold 1 , the cell sheets 2 are stacked in the mold 1 . Fill the mold 1 with a composition of transparent glass fiber-reinforced isocyanate prepolymer and polyetheramine as the front panel of the module, and remove air bubbles in it under a vacuum environment, and then heat it in an oven at 150°C for 10 minutes to complete the front panel curing molding. Then take out the front plate and put it into the mold 1, fill the composition of white glass fiber reinforced isocyanate prepolymer and polyether amine as the back plate of the component, and then complete the processing and molding by vacuum defoaming and post-heating curing. Finally, the integrated front plate, battery sheet 2 and back plate are demoulded and taken out. The front sheet and the back sheet obtained in this embodiment are respectively cured and formed by condensation polymerization.

Embodiment 2

[0057]After coating the mold release agent in the mold 1, stack the battery sheet 2 in the mold 1, inject the polymerizable monomer, crosslinking agent and initiator into the mold 1, and remove the air bubbles under an inert gas atmosphere, and then The polymerization reaction is initiated at 80°C-100°C to realize the curing of the front plate. Take out the cured front plate and cell sheet 2, put them into the mold 1 again, inject the polymerizable monomer, crosslinking agent and initiator again, and remove the air bubbles under an inert gas atmosphere, and then heat them at 80°C-100°C Initiate the polymerization reaction to realize the curing of the backsheet. Finally, the integrated front plate, battery sheet 2 and back plate are demoulded and taken out. The front sheet and the back sheet obtained in this embodiment are respectively cured and formed by free radical polymerization.

Embodiment 3

[0059] After coating the mold release agent in the mold 1, stack the battery sheet 2 in the mold 1, inject the polymerizable monomer, crosslinking agent and initiator into the mold 1, and remove the air bubbles under an inert gas atmosphere, and then The polymerization reaction is initiated at 80°C-100°C to realize the curing of the front plate. Take out the cured front plate and battery sheet 2, fill the composition of white glass fiber reinforced isocyanate prepolymer and polyether amine as the back plate of the module, and then complete the processing and molding by vacuum defoaming and post-heating curing. Finally, the integrated front plate, battery sheet 2 and back plate are demoulded and taken out. The front plate obtained in this embodiment is cured and formed by free radical polymerization, while the back plate is cured and formed by condensation polymerization.

Abstract

The invention relates to a photovoltaic module and a packaging method thereof. Front board packaging material and backboard packaging material are separately filled to the front surface and back surface of a battery piece via a mold coated with a release agent and curing treatment is performed, and thus an integrated photovoltaic module is acquired. The aluminum frame of a traditional solar cell module is not used and peeling is not needed, so that the weight of the solar cell module is reduced. The production processes of the module are simplified, and thus the packaging method of the photovoltaic module is particularly suitable for manufacturing small modules of a distributed power station. A bonding layer is not needed, and the structure is firm.

Description

technical field [0001] The invention relates to a photovoltaic module and a packaging method thereof, belonging to the technical field of solar cells. Background technique [0002] In recent years, with the further implementation of national energy conservation and emission reduction policies, photovoltaic power generation has been accepted by more and more people for its advantages of cleanness, high efficiency, and zero carbon emissions. According to statistics, in 2017, the global newly installed photovoltaic capacity reached 100GW, a year-on-year increase of 43%, and the global cumulative installed capacity reached 405GW. The traditional packaging method of solar cell modules is to stack five layers of materials such as backplane, packaging film, battery sheet, packaging film, and glass in sequence. This packaging method weighs about 20kg, which is inconvenient for transportation, carrying and installation. Therefore, developing a lightweight module has become an impor...
