Prof. Ardo was recently asked to comment on an important discovery coming out of the U.S. National Renewable Energy Laboratory (NREL). The photoelectrochemical hydrogen production team from NREL discovered that many accepted measurement protocols for solar-to-hydrogen efficiency may be flawed and the group cautioned interpretation of world record efficiencies from nearly 20 years prior. The same group then demonstrated that the previous efficiency values could be obtained with new materials using properly calibrated systems and techniques.
