Comparison of amorphous silicon absorber materials: Kinetics of light-induced degradation

Christophe Ballif, Adrian Billet, Franz-Josef Haug, Mathieu Gérard Boccard, Matthieu Despeisse, Michael Elias Stückelberger, Yannick Samuel Riesen

We investigate the influence of the deposition parameters for intrinsic amorphous silicon absorber layers on light-induced degradation (LID) of thin-film silicon solar cells. The focus is on absorber layers with different bandgaps: on one side, solar cells ...

Resistive interlayer for improved performance of thin film silicon solar cells on highly textured substrate

Christophe Ballif, Andrea Feltrin, Peter Cuony, Grégory Bugnon, Adrian Billet, Matthieu Despeisse, Michael Elias Stückelberger

The deposition of thin-film silicon solar cells on highly textured substrates results in improved light trapping in the cell. However, the growth of silicon layers on rough substrates can often lead to undesired current drains, degrading performance and re ...

Development of Micromorph Cells in Large-Area Industrial Reactor

Christophe Ballif, Andrea Feltrin, Gaetano Parascandolo, Grégory Bugnon, Adrian Billet, Matthieu Despeisse

The influences of the deposition pressure and silane depletion on the efficiency of single-junction microcrystalline silicon solar cells has been investigated. The efficiency is found to correlate with the ion energy which affects the density of states in ...

Micromorph tandem solar cells grown at high rate with in-situ intermediate reflector in industrial KAI PECVD reactors

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

We report on the latest results of tandem micromorph (a-Si:H/μc-Si:H) silicon solar cells fabricated in commercial Oerlikon Solar KAI-S and KAI-M PECVD reactors. First developments of in-situ silicon oxide based intermediate reflector (SOIR) in KAI reactor ...
