A team from the Institute of Materials Science of Seville (ICMS), a joint center of the Spanish National Research Council (CSIC) and the University of Seville (US), has developed a new hybrid device that allows energy to be captured from both the sun and rain simultaneously. A thin film created and patented by the research team not only protects and improves the durability of perovskite solar cells, even in adverse weather conditions, but also allows nanogenerators to produce more than 100 volts from the impact of a single drop of water, enough to power small portable devices.
