Influence of a Gold Seed in Transparent V 2 O x /Ag/V 2 O x Selective Contacts for Dopant-Free Silicon Solar Cells

Dielectric/metal/dielectric structures based on vanadium pentoxide with a thin silver interlayer have been optimized to replace traditional transparent electrodes. As would be expected, there is a tradeoff in the metal thickness to achieve high transparency and low sheet resistance simultaneously. It has been demonstrated that an ultra-thin gold seed prevents the tendency of silver to form cluster...
