HI ERN PhD student Ken Jeneweins study on “Accessing In Situ Photocorrosion under Realistic Light Conditions” published in ACS Measurement Science AU

21 October 2021

High-impact photoelectrode materials for photoelectrochemical (PEC) water splitting are distinguished by synergistically attaining high photoactivity and stability at the same time. With numerous efforts toward optimizing the activity, the bigger challenge of tailoring the durability of photoelectrodes to meet industrially relevant levels remains. In situ photostability measurements hold great promise in understanding stability-related properties.

In his study, PhD student Ken Jenewein has developed a photoelectrochemical scanning flow cell connected to an inductively coupled plasma mass spectrometer and equipped with a solar simulator, Air Mass 1.5 G filter, and monochromator. The established system can assess basic photoelectrochemical metrics in a reliable and high-throughput manner as well as the in-situ photocorrosion under realistic light conditions.

His study was recently published in ACS Measurement Science AU and selected as the front cover for the upcoming issue.
