Journal ArticleDOI
Current Losses at the Front of Silicon Heterojunction Solar Cells
Zachary C. Holman,Antoine Descoeudres,L. Barraud,Fernando Zicarelli Fernandez,Johannes P. Seif,S. De Wolf,Christophe Ballif +6 more
TL;DR: In this paper, the current losses due to parasitic absorption in the indium tin oxide (ITO) and amorphous silicon (a-Si:H) layers at the front of silicon heterojunction solar cells are isolated and quantified.
Journal ArticleDOI
Very low surface recombination velocities on p-type silicon wafers passivated with a dielectric with fixed negative charge
G. Agostinelli,Annelies Delabie,Petko Vitanov,Z. Alexieva,Harold Dekkers,S. De Wolf,Guy Beaucarne +6 more
TL;DR: In this paper, surface recombination velocities as low as 10 cm/s have been obtained by treated atomic layer deposition (ALD) of Al 2 O 3 layers on p-type CZ silicon wafers.
Journal ArticleDOI
>21% Efficient Silicon Heterojunction Solar Cells on n- and p-Type Wafers Compared
TL;DR: In this article, the performance of front and rear-emitter silicon heterojunction solar cells on n- and p-type wafers were experimentally investigated, and high open-circuit voltages (Vocs) were obtained on both types of float zone (FZ) wafer.
Journal ArticleDOI
Hydrogen-doped indium oxide/indium tin oxide bilayers for high-efficiency silicon heterojunction solar cells
Loris Barraud,Zachary C. Holman,N. Badel,P. Reiss,Antoine Descoeudres,Corsin Battaglia,S. De Wolf,Christophe Ballif +7 more
TL;DR: In this article, a hydrogen-doped indium oxide (IO:H) and indium tin oxide (ITO) bilayer was proposed for silicon heterojunction solar cells.
Journal ArticleDOI
Amorphous silicon passivated contacts for diffused junction silicon solar cells
James Bullock,Di Yan,Yimao Wan,Andres Cuevas,Bénédicte Demaurex,Aïcha Hessler-Wyser,S. De Wolf +6 more
TL;DR: In this paper, the authors insert thin intrinsic hydrogenated amorphous silicon [a-Si:H(i)] passivating films between the dopant-diffused silicon surface and aluminum contacts.
