A photovoltaic solar cell structure comprises a silicon substrate having a frontside and a backside, the backside having base regions and emitter regions. A tunnel dielectric covers at least a portion of the base regions and at least a portion of the emitter regions. Discrete silicon nanoparticle n+ doped polysilicon regions are on the tunnel dielectric covering the base regions. And discrete silicon nanoparticle p+ doped polysilicon regions are on the tunnel dielectric covering the emitter regions. |
