1. a manufacture method for solar cell, is characterized in that, comprising:

  • There is provided one first type doped semiconductor base material, this first type doped semiconductor base material has a first surface and a second surface relative with this first surface;

    In this first type doped semiconductor base material of part, form a Second-Type doped diffusion region, this Second-Type doped diffusion region extends in this first type doped semiconductor base material from this first surface;

    An anti-reflecting layer contacted with this Second-Type diffusion layer is formed on this first surface of this base material;

    On this anti-reflecting layer, form conducting resinl, this conducting resinl comprises a conducting particles, an admixture, a matrix, a softening agent and a binding agent;

    Carry out altogether sintering process, to make this conducting resinl form through this anti-reflecting layer the first contact conductor that is embedded in this anti-reflecting layer, in this co-sintering technique, those dopant diffusion to this Second-Type doped diffusion region to form a Second-Type heavily doped region;

    AndOne second contact conductor is formed on this second surface of this first type doped semiconductor base material,Wherein, the degree of depth of this Second-Type heavily doped region is greater than the degree of depth of Second-Type doped diffusion region.
