1. a solar cell device, comprising:

  • Silicon substrate, comprising there being the alloy be pre-existing in;

    Even lightly doped region, it is formed on the surface of described silicon substrate on the described alloy be pre-existing in, and is formed thus and tie between the described alloy that is pre-existing in and described lightly doped region;

    Heavy doping Selective implantation region, on the described surface of its described silicon substrate in described lightly doped region, forms selective emitting electrode structure thus;

    Inculating crystal layer, it is directly formed on described heavily doped region, and the width of wherein said inculating crystal layer is less than the width in described heavy doping Selective implantation region;

    AndMetal Contact, it is formed on described inculating crystal layer.
