Laser contacts from POx/Al2O3 passivation stacks
Aug 20, 2020
|• n+ laser doping demonstrated from POx/Al2O3 passivation stacks on silicon. • Metallised J0 of 540 fA cm−2 for n+ laser-doped region with Rsheet of 39.5 Ω/□. • Consistent with values for POCl3 furnace diffusions, indicating minimal defects. • Same POx/Al2O3 stack provides J0 of 2.5 fA cm−2 on undiffused planar surfaces. • 23.6% simulated efficiency for laser-doped n-type PERL cell based on POx/Al2O3.
