Overview Research Education Media Contact
My passions are material science research, education and art. My research group's work focusses on the development and understanding of functional optoelectronic thin film materials: hybrid halide perovskites, transparent conducting oxides (TCOs) and p-type transparent conducting materials. We explore and develop physical vapour deposition (PVD) techniques to achieve thin film growth control, tune optoelectronic material properties and even discover new materials. Our optoelectronic thin film materials find application in energy conversion and/or efficient devices like solar cells, light emitting diodes, photonics andĀ transparent electronics.
Before coming to UTwente, I have beenĀ team leader for the transparent electrodes development at theĀ Photovoltaics and Thin-Film Electronics Laboratory (PVLab) of the Ecole Polytechnique Federale de Lausanne (EPFL), Switzerland. I obtained my Ph.D. in Physics from Leiden University, The Netherlands in 2012, working on resistive switching memories.
