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.



The KPV-LAB attracts qualified researchers from different countries across the world.

Growing 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.
