Journal ArticleDOI
Is the Cu/Zn disorder the main culprit for the voltage deficit in kesterite solar cells?
S. Bourdais,Christophe Chone,Bruno Delatouche,Alain Jacob,Gerardo Larramona,Camille Moisan,Alain Lafond,Fabrice Donatini,Fabrice Donatini,Germain Rey,Susanne Siebentritt,Aron Walsh,Aron Walsh,Gilles Dennler +13 more
TL;DR: In this article, the role of anionic (S/Se) distribution and cationic (Cu/Zn) disorder on the open-circuit voltage (Voc) and the ultimate photovoltaic performance of kesterite devices is clarified.
Journal ArticleDOI
On the origin of band-tails in kesterite
Germain Rey,Gerardo Larramona,S. Bourdais,Christophe Chone,Bruno Delatouche,Alain Jacob,Gilles Dennler,Susanne Siebentritt +7 more
TL;DR: In this paper, the authors show that the band-tailing originates mainly from band-gap fluctuations attributable to chemical composition variations at nanoscale; while electrostatic fluctuations play a lesser role.
Journal ArticleDOI
Fine‐Tuning the Sn Content in CZTSSe Thin Films to Achieve 10.8% Solar Cell Efficiency from Spray‐Deposited Water–Ethanol‐Based Colloidal Inks
Gerardo Larramona,Sergiu Levcenko,S. Bourdais,Alain Jacob,Christophe Chone,Bruno Delatouche,Camille Moisan,Justus Just,Thomas Unold,Gilles Dennler +9 more
TL;DR: In this paper, the authors proposed to tune the Sn content in the precursor ink to optimize the performance of the CZTSSe layers of thin film solar cells and achieved a 10.0% performance with antireflection coating.
Journal ArticleDOI
8.6% Efficient CZTSSe Solar Cells Sprayed from Water-Ethanol CZTS Colloidal Solutions.
Gerardo Larramona,S. Bourdais,Alain Jacob,Christophe Chone,Takuma Muto,Yan Cuccaro,Bruno Delatouche,Camille Moisan,Daniel Péré,Gilles Dennler +9 more
TL;DR: The achievement of cell efficiencies up to 8.6% under AM1.5G and without antireflecting coating indicates that this method can compete with other vacuum-based or more complex wet deposition methods.
Journal ArticleDOI
Nanocrystalline solar cells with an antimony sulfide solid absorber by atomic layer deposition
Hannes Wedemeyer,Jan Michels,Radoslaw Chmielowski,S. Bourdais,Takuma Muto,Mikio Sugiura,Gilles Dennler,Julien Bachmann,Julien Bachmann +8 more
TL;DR: Extremely thin absorber solar cells are built in which an Sb2S3 absorber coating is created by atomic layer deposition (ALD) The material is distributed homogeneously along the depth axis and is free of oxide as mentioned in this paper.
