Solar cells’ (SCs) technologies are among the most capable alternative energy trends. One of the key components of any SC device is the metal contacts, which greatly determine their efficiency, stability, and cost. The utilization of Cu-based multi-layered thin-film contacts instead of commonly used Ag-based screen-printed electrodes is a promising alternative for the SCs’ cost and size reduction, while maintaining high electrical conductivity. The long-term stability of Cu-based contacts could be improved by the post-fabrication processing. Our recent studies on Ni/Cu/Cr/Si(001) films show their increased oxidation resistance and decreased O and C impurities content after the films’ low-energy (<2000 eV) Ar+ ion irradiation. Furthermore, ion pre-irradiation significantly promotes the wear resistance of thin-films subjected to annealing in vacuum. These findings are of relevance for the development of durable and low-cost contacts for the novel thin-film hetero-junction silicon SCs.
