Alexander R. Uhl

Dr. Alexander R. Uhl is an Associate Professor at the Okanagan School of Engineering, University of British Columbia, holding the Principal's Research Chair in Solar Energy Conversion. His research focuses on solution-processed solar cells, including chalcogenide and perovskite absorbers, with an emphasis on scalable, low-cost fabrication methods. He has achieved world-record efficiencies in CuIn(S,Se)₂ solar cells.

• Education: PhD in Materials Science & Engineering from ETH Zurich; Diploma in Nanoscale Engineering from University of Würzburg
• Postdoctoral Experience: University of Washington (with Hugh Hillhouse) and EPFL (with Michael Grätzel)

His research program addresses three key areas:

• Solution-processed thin film solar cells
• Tandem photovoltaic devices
• Photoelectrochemical CO₂ reduction for solar fuels

Dr. Uhl has published in journals like Nature Energy, Science Advances, and Advanced Energy Materials, with recent work on 22%+ efficient perovskite cells and rear surface passivation techniques. He has filed two patents on solution-processed chalcogenide solar cells.

Scientific Recognition:

• Principal's Research Chair in Solar Energy Conversion
• Three-time Swiss National Science Foundation Fellow
• Invited book chapter on perovskite solar cell counter electrodes

He supervises graduate students and teaches courses in materials science and alternative energy systems. His lab (LSEF) develops technologies aiming to surpass coal-equivalent electricity prices through ink-jet printing and high-throughput manufacturing.
