Hybrid nanomaterials as powerhouses for miniature energy storageThe development of new electronics requires a search for materials with unprecedented properties. For example, for local electrical energy storage on a chip and very fast charge-discharge thereof, so-called miniaturized pulsed-power devices, special ferroelectric materials are being studied. Scientists of the Inorganic Materials Science group (MESA+ Institute, University of Twente) alternate thin layers of two materials, lead zirconate (PbZrO3 – PZ) and lanthanum-doped lead zirconate titanate (Pb0.9La0.1Zr0.52Ti0.48O3 – PL) and show that the favorable properties of both materials reinforce each other in a multilayer. In addition, the layering also ensures that the maximum voltage that can be applied is significantly higher. These factors result in a strongly enhanced recoverable energy-storage density (increased by a factor of 4 to 128.4 J/cm3) with high release efficiency (81.2%). Moreover, the multilayer films are very robust, even after many charging cycles. The results were recently published in the leading journal Advanced Energy Materials.Read more
Best poster award for Tatiana Soto MonteroTatiana Soto Montero, PhD at the M3 Optoelectronic Materials team part of IMS, won the best poster award (scientific contribution) at the 2nd International tandemPV Workshop, hosted by Fraunhofer ISE, Germany. The workshop took take place as a hybrid event in the brand new soccer stadium of SC Freiburg (Europa-Park Stadion) in close proximity to the Fraunhofer Institute for Solar Energy Systems (ISE). The title of the winning poster is “Single-Source Vapor-Deposited MA1–xFAxPbI3: From Mechanochemical Synthesis to Thin Films” by Tatiana Soto Montero, Suzana Kralj, Wiria Soltanpoor, Junia Solomon, Chris Baeumer, Monica Morales-Masis.
