SunDrive replaces silver with 100X cheaper copper for its 25.54% efficiency record setting commercial solar cells

https://www.pv-magazine-australia.com/2021/09/10/australian-start-up-sets-25-54-efficiency-record-for-silicon-cell/

"Copper doesn’t have the same highly conductive properties as silver and does not adhere well to the surface of the solar cell but Sydney-based solar technology start-up SunDrive... has found a solution... aim is to produce the cells locally, optimistic that they can compete with large solar manufacturers in Asia"
