Provided by the Springer Nature SharedIt content-sharing initiative We present a simulation-based study for identifying promising cell structures, which integrate poly-Si on oxide junctions into industrial crystalline silicon solar cells. The simulations use best-case measured input parameters to determine efficiency potentials.
The application of polysilicon contacts to solar cells is not new, but it is undergoing a revival. Some researchers deposit an in-situ doped amorphous or polycrystalline silicon layer by PECVD using phosphine and silane . Alternatively, ion implantation followed by a thermal step can be used to dope intrinsic polysilicon , .
Silicon solar cell architectures featuring poly-Si based junctions are poised to become the next evolutionary step for mainstream silicon PVs, paving the way toward an average industry cell efficiency of 25% over the next decade.
Other studies of ion implanted and thermally activated polysilicon layers have demonstrated very low recombination current densities J0 ∼1 fA/cm 2 for n + polysilicon and ∼4.4 fA/cm 2 for p + polysilicon , , which shows the great potential of doped polysilicon as a passivated contact for solar cells.
Ideally, a finished 166 mm solar cell with a thickness of 175 μm contains ≈11.2 g of poly-Si. With an efficiency of 22.8% based on an industrial passivated emitter and rear contact (PERC) cell, [ 9 ] the estimated poly-Si consumption is 1.79 kt GW −1.
