The intermittent character of solar-energy and the need to store it efficiently is undoubtedly the Achille’s heel of current photovoltaic/energy storage systems like silicon solar panels and big batteries characterized by high costs of installation and maintenance and by large sizes and high weight.
The LIGHT-CAP European project, which started in January and will last four years, will launch a disruptive technology that combines energy conversion and storage into one single compact unit with low volume and weight, based on environmentally friendly and Earth abundant materials. LIGHT-CAP’s science enabled hybrid technology is based on the exploitation of the cooperative electronic properties of zero-dimensional and two-dimensional nano-materials, which take over the role of both the light energy conversion and storage, together with the unique opportunity to accumulate multiple delocalized charges per nanostructural unit after photo-activation. Thus, LIGHT-CAP merges solar-powered energy storage with multi-charge transfer capability. Superior stability of the active components is given by the delocalization of the stored charges with respect to most conventional organic redox couples, and the further gain of prospectively enhanced light-powered energy density. The achievement of the LIGHT-CAP’s ambitious objectives will contribute to a future sustainable and zero-emission energy landscape in Europe.
The project consortium encompasses an interdisciplinary community made up of Fondazione Istituto Italiano di Tecnologia (IIT), École Polytecnique Fédérale de Lausanne (EPFL), Technische Universität Dresden (TUD), Justus-Liebig-Universität Gießen (JLU), Politecnico Di Milano (POLIMI) and IMDEA Energy, it is funded by the call H2020-FETPROACT-2018-2020 - FET Proactive: Boosting emerging technologies
