The invention provides a welding-free photovoltaic module and a processing method, and relates to the field of manufacture of photovoltaic power generation equipment. The welding-free photovoltaic module comprises a face plate and a back plate, wherein a plurality of photovoltaic cell pieces are arranged between the face plate and the back plate; an upper connecting layer and a lower connecting layer are arranged between each photovoltaic cell piece and the face plate as well as between each photovoltaic cell piece and the back plate, a front connecting band and a back connecting band are arranged between each upper connecting layer and the corresponding photovoltaic cell piece as well as between each lower connecting layer and the photovoltaic cell piece, one end of each connecting band does not exceed the boundary of the photovoltaic cell piece, the other end exceeds the boundary and folds back to form a back-fold part I and a back-fold part II, the back-fold part I is located on one side of the photovoltaic cell piece, the back-fold part II is located on the other side, and the back-fold part I is bonded to a back-fold part II of an adjacent photovoltaic cell piece. According to the processing method, a tin-coating solder strip and a soldering flux are not needed, environmental pollution is avoided, the problem of cell piece cracking caused by welding stress is solved, and energy consumption for welding can be reduced.
