The invention discloses a processing method of a photovoltaic module and the photovoltaic module. The processing method of the photovoltaic module comprises the following steps that a plurality of welding strips are arranged on the two sides of a photovoltaic cell piece, a plurality of thin grid lines are arranged on the surfaces of the two sides of the photovoltaic cell piece respectively, the welding strips and the thin grid lines are arranged in a crossed mode, and heat treatment is conducted on the photovoltaic cell piece and the welding strips after the welding strips and the photovoltaic cell piece are stacked. The heat treatment temperature is higher than the melting point of the solder strip, and the solder strip and the battery piece are welded. Every two adjacent photovoltaic cells are conductively connected through a plurality of solder strips to form a cell string. Packaging adhesive films and cover plates are arranged on the front surfaces and the back surfaces of the plurality of battery strings
