The VP2 project is focusing on four grand-challenge problems, which
consist in identifying optimal materials for solar cells, for water-splitting catalysts, for solid-state ionic conductors, and for low-dimensional materials. Each of the research teams involves researchers from VP2, from the horizontal projects of MARVEL, and experimental partners. All projects are growing towards material searches on databases through the AiiDA platform (PP6). The scientific output achieved so far is impressive. However, the full potential of VP2 still lies ahead, as the synergies continue to grow and the material searches enter an operative phase.
