Influence of pressure and silane depletion on microcrystalline silicon material quality and solar cell performance

Christophe Ballif, Grégory Bugnon, Julien Claude Bailat, Andrea Feltrin

Hydrogenated microcrystalline silicon growth by very high frequency plasma-enhanced chemical vapor deposition is investigated in an industrial-type parallel plate R&D KAI (TM) reactor to study the influence of pressure and silane depletion on material qual ...

Silane depletion dependent ion bombardment and material quality of microcrystalline silicon deposited by VHF-PECVD

Christophe Ballif, Grégory Bugnon, Julien Claude Bailat, Andrea Feltrin

Microcrystalline silicon is a composite material embedding silicon nanocrystals in an amorphous matrix [1]. It has attracted much research efforts in the photovoltaic domain [2], because of its potential for integration in a tandem cell concept as bottom c ...

Influence of ion bombardment on microcrystalline silicon material quality and solar cell performances

Christophe Ballif, Grégory Bugnon, Julien Claude Bailat, Andrea Feltrin, Fanny Sculati-Meillaud

Microcrystalline hydrogenated silicon growth with VHF-PECVD was examined in an industrial type parallel plate KAITM reactor. The influence of pressure on material quality was studied in single junction solar cells. Solar cells with their intrinsic layer pr ...
