摘要： The present disclosure provides a passivation contact structure for a solar cell and a manufacturing method therefor and a solar cell using the passivation contact structure. The passivation contact structure comprises a tunnel layer; a transparent conductive film, located on the tunnel layer and in contact with the tunnel layer; a cover layer, located on the transparent conductive film; and a metal electrode, passing through the cover layer to be in contact with the transparent conductive film, the end surface of metal electrode being located in the transparent conductive film. According to the passivation contact structure for the solar cell, the manufacturing method therefor, and the solar cell using the passivation structure of the present disclosure, both electricity conducting and passivation effects can be achieved, and the effect of reducing the loss of light absorption can also be achieved.
