Gallium Contacts on p-type Silicon Substrates

Stuckings, Michael; Fischer, B; Giroult, G; Cuevas, Andres; Stocks, Matthew; Blakers, Andrew


A significant reduction in contact resistance of palladium/silicon contacts was realised by the use of a thin intermediate gallium layer. The contact resistance of the palladium/gallium/silicon contact was found to be similar to aluminium/silicon contacts on 0·5 Ω cm silicon. Solar cells processed on 1 Ω cm substrates with this structure demonstrated better contact properties than conventional aluminium/silicon contacts. The improved characteristics are believed to be a result of...[Show more]
