Lead halide perovskites are not ferroelectric: further research is needed to discover why they are so good for solar cells
- Perovskites promise to be the next star material for solar cells, but the reason of their high efficiency is still unknown.
- Researchers at the Institute of Materials Science in Barcelona (ICMAB-CSIC) and the Helmholtz-Zentrum Berlin für Materialien und Energie (Germany) have demonstrated with a new microscopy technique that perovskites are not ferroelectric, as was thought.
- The new technique, patented by CSIC in 2017, is the direct piezoelectric force microscopy (DPFM) which, for the first time, is used in lead halide perovskite solar cells.

A new laser-based technique developed by the Institute of Materials Science (ICMAB-CSIC) uses urea, a common substance in the chemical industry and a low-cost alternative to noble metal co-catalysts, to enable a more efficient, one-step production of hybrid graphene-based organic-inorganic composite layers for environmental remediation; photodegradation of antibiotic contaminants from wastewater. The composition and chemical bonds of the urea-enriched thin layers were studied in detail using synchrotron light at the ALBA Synchrotron.
Anna Laromaine in People First: “Tener mentores y referentes es importantísimo para elegir una profesión”
Anna Laromaine, researcher at the N&N group at ICMAB, was interviewed by People First, a platform where people from different institutions and enterprises are highlighted. Anna, included in the Top 100 Women more influent in Spain, and awarded in 2016 with the L'Oréal-Unesco For Women in Science Research Award, describes her work as a researcher in nanomedicine, talks about the future of nanotechnology and women in science, about her role models in life, and about being a researcher, a university teacher and an entrepreneur at the same time.
Núvol, the digital newspaper about culture, published on 28 December 2018 an article entitled "Escletxes per incloure la dona en la ciència" about our participation in the "Science & Tech Girls Vallès" event, which took pace on 17 November 2018 at the Biblioteca Vapor Badia (Sabadell).
Ferran Macià, researcher at the MULFOX group at ICMAB, and at the University of Barcelona (Fundamental Physics Department) is co-author of the article "Subnanosecond magnetization dynamics driven by strain waves" published in the MRS Bulletin, the monthly Material Science publication with technical theme topics, news, reviews, and commentary.
The studies "Synchrotron tts-µXRD identification of secondary phases in ancient ceramics" published in Heritage Science, and "Breaking Preconceptions: Thin Section Petrography For Ceramic Glaze Microstructures" published in Minerals are now featured in UABDivulga. These two articles, in which researchers from the UAB and the ICMAB have collaborated, refute the common perception of thin-sections as an old-fashioned laboratory preparation and show how this sample format conceived in the 19th century is still in force and can be adapted to the research and the new tools of the 21st century, such as the synchrotron facilities.
- Material engineering at the nanoscale can be successfully employed in the design of a new type of materials: this is the case of superlattices formed by layers the same material with different crystal structure.
- The study, published in Nano Letters, paves the way for efficient thermoelectric and nanoelectronic devices, which require high quality materials without defects within their structure and interfaces.
A general quantum-mechanical method to address spatial dispersion effects: flexoelectricity and dynamical quadrupoles
Published in Physical Review X a study which, by combining the “long-wave method,” a mainstay of condensed-matter theory since the 50s, with modern electronic-structure techniques, researchers obtain highly accurate predictions of physical responses of crystals to nonhomogenous external perturbations. A great work by Miquel Royo and Massimiliano Stengel!
On 29 March 2019, the Presidency of the CSIC signed the institutional mandate of Open Access. It is a strong impulse for the open access of different types of CSIC research results, including peer-reviewed publications and associated research data, through the DIGITAL.CSIC repository.
