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

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

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 ...

The boron-tailing myth in hydrogenated amorphous silicon solar cells

Christophe Ballif, Franz-Josef Haug, Matthieu Despeisse, Grégory Bugnon, Michael Elias Stückelberger

The boron-tailing effect in hydrogenated amorphous silicon (a-Si:H) solar cells describes the reduced charge collection specifically in the blue part of the spectrum for absorber layers deposited above a critical temperature. This effect limits the device ...

Field-effect passivation on silicon nanowire solar cells

Anna Fontcuberta i Morral, Esther Alarcon Llado, Stefaan De Wolf, Bénédicte Demaurex, Anna Dalmau Mallorquí, Amirreza Kiani

Surface recombination represents a handicap for high-efficiency solar cells. This is especially important for nanowire array solar cells, where the surface-to-volume ratio is greatly enhanced. Here, the effect of different passivation materials on the effe ...

Amorphous silicon enhanced metal-insulator-semiconductor contacts for silicon solar cells

Aïcha Hessler-Wyser, Stefaan De Wolf, Bénédicte Demaurex

Carrier recombination at the metal-semiconductor contacts has become a significant obstacle to the further advancement of high-efficiency diffused-junction silicon solar cells. This paper provides the proof-of-concept of a procedure to reduce contact recom ...
