Photovoltaic module preparation method

The invention discloses a photovoltaic module preparation method, which is characterized in that after battery pieces are prepared, the prepared battery pieces and an isolation assembly are arranged in a laminated manner, so that the isolation assembly isolates two adjacent battery pieces to form a first battery piece stack, and the isolation assembly comprises an isolation piece and a plurality of air bags; the separator is provided with a plurality of vent holes, the plurality of air bags are respectively connected with the separator, the plurality of air bags are respectively distributed on the same side of the separator at intervals, and one side, provided with the air bags, of the separator is in contact with the blue diaphragm of the battery piece. The air bag is arranged on one side of the separator, and the air bag is in contact with the blue diaphragm of the battery piece, so that the friction force between the blue diaphragm and the isolation assembly can be counteracted by the left-right swinging o
