A consensus statement establishes the protocols to assess and report stability of perovskite photovoltaic devices

The existing characterization procedures to evaluate emerging photovoltaic devices are not appropriate for halide perovskite solar cells, a new generation of solar cells called to overcome the present state-of-the-art technologies. A vast group of scientists, led by Prof. Mónica Lira-Cantú (ICN2) and Prof. Eugene A. Katz (Ben-Gurion University of the Negev), have reached a consensus on the suitable procedures and the variables to be reported in stability studies of this kind of solar cells. The consensus statement, highlighted in the last issue of Nature Energy, updates the ISOS protocols for the stability assessment of perovskite photovoltaics with additional procedures to account for properties specific to this technology.

Generation and manipulation of spin currents for advanced electronic devices

ICN2 researchers, in the framework of the Graphene Flagship, demonstrate that spin currents can be generated and manipulated in graphene-based heterostructures at room temperature. The results of this study, published in Nature Materials, provide relevant information on the fundamental physics of the phenomena involved and open the door to new applications, such as the development of ultra-compact electronic and low energy consumption devices and magnetic memories.
