摘要： A partial tunneling oxide layer passivation contact structure of a photovoltaic cell and a photovoltaic module, wherein the partial tunneling oxide layer passivation contact structure of the photovoltaic cell comprises a cell body, a first tunneling oxide layer disposed on the surface of the cell body, and a first polysilicon thin film layer disposed on the surface of the tunneling oxide layer, wherein the surface of the cell body comprises a passivation contact area and a light absorption area, the first tunneling oxide layer is arranged in the passivation contact area, and the projection of the first polysilicon film layer on the surface of the cell body is in the passivation contact area. The first tunneling oxide layer and the first polysilicon thin film layer only cover the passivation contact area, which improves the passivation level in this area and reduces the recombination of the cell surface, however, the first tunneling oxide layer and the first polysilicon film layer are not in the light absorption area, that is, a non-metal contact area, which reduces the shielding of sunlight and improves the light absorption efficiency.
