The invention belongs to the technical field of a photovoltaic module, and particularly relates to a photovoltaic module and a packaging process. An EVA adhesion thin film I (2) is glued on the innerside of a piece of inversely buckled U-shaped tempered glass (1); a photovoltaic chip (3) is arranged at the lower end of the EVA adhesion thin film I (2) I; an EVA adhesion thin film II (4) is arranged at the lower end of the photovoltaic chip (3); a supporting back plate (5) is arranged at the lower end of the EVA adhesion thin film II (4); the lower end of the supporting back plate (5) is fixedin the middle of a U-shaped aluminum groove (6); the outer side of the U-shaped aluminum groove (6) packages the outer side of the inversely buckled U-shaped tempered glass (1); and a fixed liquid adhesive (7) is arranged in the connecting place of the inversely buckled U-shaped tempered glass (1) and the U-shaped aluminum groove (6). By adoption of a pair of mutually buckled U-shaped sealing buckles, the photovoltaic modules are compressed together, so that the sealing property of the photovoltaic module is improved, and the problem of partial damage of the photovoltaic chip caused by non-tight packaging can be avoided.
