Description du projet
Une nouvelle unité compacte pour récolter et stocker l’énergie solaire
Le projet LIGHT-CAP, financé par l’UE, entend mettre au point une technologie écologique pour exploiter efficacement l’énergie solaire. Pour ce faire, il prévoit de combiner la conversion et le stockage de l’énergie dans une unité unique, compacte et légère. L’idée innovante de la technologie hybride de LIGHT-CAP repose sur l’exploitation des propriétés électroniques coopératives des nanomatériaux à zéro et à deux dimensions et sur le potentiel des charges électriques délocalisées après photoactivation. Cette technologie de rupture fera l’objet de démonstrations dans des dispositifs analogues aux piles, aux supercondensateurs hybrides et aux condensateurs électrolytiques. LIGHT-CAP réunira des équipes multidisciplinaires venues d’Allemagne, d’Italie, d’Espagne et de Suisse.
Objectif
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. LIGHT-CAP will launch a long-term technological vision in Europe that combines energy conversion and storage into one single compact unit with low volume and weight, based on environmentally friendly and Earth abundant materials, with the additional cost benefit delivered by solution processing. 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. This disruptive technology will be demonstrated in devices designs analogous to cell batteries and hybrid electrolytic-like/super-capacitors with the added value of being powered by the quasi infinite availability of the sun. To this aim LIGHT-CAP encompasses an interdisciplinary community that will stimulate the genesis of a novel Europe-based innovation eco-system around the new technological paradigm with a direct impact on portable and mobile electronics, simultaneously setting the basis for its future exploitation in large area systems too. The achievement of the LIGHT-CAP’s ambitious objectives will contribute to a future sustainable and zero-emission energy landscape in Europe.
