A supercomputer capable of carrying out up to 1.4 million billion mathematical operations per second, a state-of-the-art laboratory for the realization of innovative and high-efficiency solar cells, but also relevant expertise for the development of sustainable photovoltaic modules. These are the resources that ENEA, through the Department of Energy Technologies and Renewable Sources, is making available to the VIPERLAB project, which aims to promote the research and development of perovskite-based photovoltaic devices through access to 13 of Europe's leading research infrastructures specializing in the fabrication, characterization, calculation and modeling of perovskite-based photovoltaic devices. The activities were presented just days before the International Day of the Sun, which falls tomorrow, to promote the great potential of solar energy, which is environmentally and climate friendly and an important contributor to the energy transition, including through support for industry and the creation of new production chains.
