RT Journal Article T1 High Pressure Sputtering of materials for selective contacts in emerging photovoltaic cells A1 San Andrés Serrano, Enrique A1 García Hernansanz, Rodrigo A1 Patricia Moreno, Gloria A1 García Hemme, Eric A1 Barrio, Rocío A1 Torres Almarza, Ignacio A1 Caudevilla Gutiérrez, Daniel A1 Pastor Pastor, David A1 Olea Ariza, Javier A1 Prado Millán, Álvaro Del A1 Algaidy, Sari A1 Zenteno Pérez, Francisco AB In this work we have explored the growth by high pressure sputtering (HPS) of materials intended for novel selective contacts for photovoltaic cells. This technique shows promise for the low-damage low-temperature deposition of PV materials. We studied the deposition of ITO, MoOx and TiOx using pure Ar and mixed Ar/O2 atmospheres as well as ceramic or metallic targets. We show that HPS deposition of these materials is feasible. The growth rate is greatly reduced when oxygen is added to the argon sputtering atmosphere. The best sputtering RF power was 20-45 W for the pressure range studied. Finally, as-deposited films present high surface recombination, but a mild hot plate anneal at 200ºC recovers long effective lifetimes.
