Activation of NiFe oxide-based OER catalysts: Iron determines the growth of the catalytically active phase in NiO Open
Mixed nickel iron hydr-/oxides are nowadays the best performing alkaline O2 evolution electrocatalysts. It has been assumed that the activity of these catalysts is determined by surface species but that a conditioning of the bulk is necess…

Effect of Metal Layer Support Structures on the Catalytic Activity of NiFe(oxy)hydroxide (LDH) for the OER in Alkaline Media Open
Photoelectrochemical (PEC) cells promise to combine the benefits of photovoltaics and electrolysis in one device. They consist of a photoabsorber functionalized with an electrocatalyst to harvest faradaic currents under reduced overpotenti…

Removal of Surface Oxygen Vacancies Increases Conductance Through TiO<sub>2</sub> Thin Films for Perovskite Solar Cells Open
We report that UV-ozone treatment of TiO2 anatase thin films is an efficient method to increase the conductance through the film by more than 2 orders of magnitude. The increase in conductance is quantified via conductive scanning force mi…

How the formation of interfacial charge causes hysteresis in perovskite solar cells Open
In this study, we use time-resolved Kelvin probe force microscopy to investigate current–voltage hysteresis in a hybrid lead-halide perovskite solar cell.
