There is provided a photoelement such as a solar cell including a copper-containing metallic lattice structure containing as a diffusion barrier a metal-phosphorus layer. The copper-containing metallic lattice structure includes, from bottom to top, a metal-phosphorus plated layer containing neither copper nor a copper alloy and disposed within a lattice structure formed on a front surface of a semiconductor substrate, and a plated copper-containing layer. Further, there is also provided a method of forming such a structure. |
