摘要（英）：

The utility model provides an IBC battery structure. Wherein the tunneling oxide layer, the first doping layer and the second doping layer are arranged on the back face of the base body, the first doping layer is arranged on the side, opposite to the base body, of the tunneling oxide layer, and the second doping layer is located on the back face of the base body and is opposite to a through groovepenetrating through the tunneling oxide layer; the first doped layer is provided with a first back passivation layer, and the second doped layer is provided with a second back passivation layer. TheIBC battery structure provided by the utility model can have higher open-circuit voltage, thereby being beneficial to realizing higher conversion efficiency.
