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 sunny and hot climates. Our research efforts are focused on "Silicon Heterojunction Solar Cells", "Perovskite Solar Cells", "Perovskite/Silicon Tandem Solar Cells", and "Perovskite/Perovskite Tandem Solar Cells".
The KPV-LAB has strong collaborations with respected academic researchers and industrial partners.
Perovskite/Perovskite Tandem Solar Cells
We develop perovskite/perovskite tandem solar cells aiming at>30% power conversion efficiency with Pb/Sn-based low bandgap rear cells.
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)
19 September, 2021Numerical Modeling Predict the Performance of Ultra-Thin Devices
In the latest work, Dr. Waseem Raja and his colleagues develop a novel 3-D opto-electrical finite-element model to analyze the performance of ultrathin solar cells. Overall, the study shows how 3-D finite element modeling can aid in analyzing and developing new optical and electrical solar cell designs for ultra-thin solar cells such as those based on chalcogenides and perovskites.
04 September, 2021Minding the gaps to boost perovskite performance
In collaboration with LAMA, OMEGA, CPMS, and UFD groups of KAUST, we have shown that phenformin hydrochloride (PhenHCl), a multifunctional molecule that plugs various atomic-scale defects in perovskite solar materials, can significantly boost the longevity and electrical output of perovskite-based solar cells.
16 August, 2021We test our perovskite/silicon tandem directly under the Sun!
In his latest work, Dr. De Bastiani led the KPVLAB team, in collaboration with the University of Toronto and the EPFL, through a six-month outdoor performance study of bifacial perovskite/silicon tandems in the sunny and humid desert of Saudi Arabia.
