A metallization paste or ink for making electrical contacts on solar cells has reduced diffusion in a silicon wafer. The paste or ink is configured for printing on a crystalline silicon substrate of a solar cell, wherein the paste comprises silicon particles, aluminum particles, and a paste vehicle. Alternatively, the paste comprises aluminum-silicon alloy particles.

Metallization paste for solar cells

For solar cell fabrication, the addition of precursors to printable media to assist etching through silicon nitride or silicon oxide layer thus affording contact with the substance underneath the nitride or oxide layer. The etching mechanism may be by molten ceramics formed in situ, fluoride-based etching, as well as a combination of the two.
