KAUST Photovoltaics Laboratory
The KPV-LAB brings international researchers together to develop high-efficiency solar cells
Welcome to the KAUST Photovoltaics-Laboratory (KPV-LAB) webpage
The KPV-LAB is led by Stefaan De Wolf of the Material Science & Engineering Program at King Abdullah University of Science and Technology (KAUST).
At KPV-LAB, we are dedicated to developing a realistic high-efficiency photovoltaic solution for hot climates. Our research efforts are focused on "Silicon Heterojunction Solar Cells", "Perovskite Solar Cells", and "Perovskite/Silicon Tandem Solar Cells".
The KPV-LAB has strong collaborations with respected academic researchers and industrial partners.
Novel Transparent Conductive Oxide Electrodes
ITO, IZO, IZrO, H: In2O3, AZO are some of the successful materials have been developed at KPV-LAB
Perovskite/Silicon Tandem Solar Cells
The KPV-LAB develops novel perovskite/silicon tandem solar cells aiming >30% power conversion efficiency
Novel Carrier Selective Contacts by ALD
High-Efficiency Perovskite Solar Cells
KPV-LAB focuses on developing large-area compatible fabrication methods for high-performance perovskite solar cells
Silicon Heterojunction Solar Cells
One of the main research activities of KPV-LAB is focused on the development of high-efficiency silicon heterojunction solar cells (SHJ)

Mechanically stacked tandems still hold great potential. Check out our collaborative study with @Sargent_Group reporting lab-scale 28.2% perovskite/silicon tandems with 19% semitransparent top cells published in Nature Communications.
05 March, 2020Growing perovskite on textured silicon - check out KPV-LAB's recent study in Science Magazine
Our team in a collaboration with Sargent Group grew thick films of perovskite with a bandgap of ∼1.68 electron volts and used a passivant, 1-butanethiol, to limit its phase separation. The tandem cells had a certified power conversion efficiency of 25.7% and had negligible losses after 400 hours of operation.
