Review: Progress in solar cells from hydrogenated amorphous silicon

Christophe Ballif, Franz-Josef Haug, Michael Elias Stückelberger, Rémi Biron

Hydrogenated amorphous silicon (alpha-Si:H) has been used for decades doped and as intrinsic absorber layers in thin-film silicon solar cells. Whereas their effiency was improved for a long time by the deposition of higher quality absorber layers, recent i ...

Temperature dependence of hydrogenated amorphous silicon solar cell performances

Christophe Ballif, Franz-Josef Haug, Michael Elias Stückelberger, Yannick Samuel Riesen

Thin-film hydrogenated amorphous silicon solar (a-Si:H) cells are known to have better temperature coefficients than crystalline silicon cells. To investigate whether a-Si:H cells that are optimized for standard conditions (STC) also have the highest energ ...

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 ...
