Martijn Wienk is an Assistant Professor at Eindhoven University of Technology (TU/e) in the Department of Chemical Engineering and Chemistry. He is affiliated with the Molecular Materials and Nanosystems (M2N) research group and the Institute for Complex Molecular Systems (ICMS Core), with his office located at Helix-west 4.36. His research focuses on the optimization and characterization of solution-processed hybrid polymer-metal oxide solar cells, with particular emphasis on perovskite solar cells. Dr. Wienk investigates how morphology of active layers affects device performance, especially in ZnO:polymer hybrid systems where polymer hydrophilicity controls ZnO distribution. His current work addresses critical challenges in photovoltaics including interfacial losses, non-radiative recombination mechanisms, and stability issues in narrow-bandgap perovskite materials. Analysis of his recent publications reveals significant contributions to perovskite solar cell technology. His research demonstrates how additives like glycine hydrochloride improve narrow-bandgap perovskites by retarding Sn²⁺ oxidation and enhancing crystallization. He has also developed substrate functionalization techniques using compounds like 1,6-hexylenediphosphonic acid to reduce nonradiative losses, and investigated interface engineering strategies for tandem solar cells used in solar water splitting applications achieving 17.8% solar-to-hydrogen efficiency. His scientific contributions include: Investigating bulk and interface contributions to voltage losses in perovskite solar cells Developing effective passivation strategies for narrow-bandgap perovskites Advancing understanding of degradation mechanisms in all-perovskite tandem systems Improving fundamental knowledge of charge carrier dynamics in hybrid photovoltaic materials Dr. Wienk collaborates extensively with Professor René A.J. Janssen and other researchers at TU/e. His work is supported by funding from the Dutch Research Council (NWO), the European Research Council (ERC), and industry partners including HyET Solar BV. He contributes to UN Sustainable Development Goals related to affordable and clean energy through his research on next-generation photovoltaic technologies. Within the Molecular Materials and Nanosystems group, Dr. Wienk leads research activities focused on developing stable, high-efficiency photovoltaic materials while mentoring students and contributing to educational programs including 'DBL Energy', 'Nanomaterials: chemistry and fabrication', 'DBL Nanotechnology', and 'CBL Molecules and Materials'.
