Jacinto Sa group
Plasmonic nanosystems
Our research
Jacinto Sá's research group investigates fundamental aspects of plasmonic materials, with emphasis on applications to photocatalysis and photovoltaics. Plasmonic materials absorb ten time more light than any other material offering the prospect of low-cost solar energy conversion. However, there is a significant knowledge gap in how they operate. Our research is focused on the development and understanding of plasmon-based systems capable of producing fuel and high-value chemicals with light (artificial photosynthesis) and make solar electricity (direct plasmonic solar cells) for smart things, like IoT sensors and wearables. We use advanced spectroscopy to gain fundamental understanding of the underlying processes.
