Jacinto Sa group

Plasmonic nanosystems
Our research
My research group studies the fundamental interactions between light and matter, with a focus on how light is converted into electrical charges in plasmonic systems and induces near-field effects.
Using advanced laser-based spectroscopies, we track these processes in real time. The insights we gain inform the design of photosystems for chemical production and nanophotonic applications.
This latter work led to the creation of Duck Technologies, a company developing advanced coatings to mitigate overheating problems.
Short presentation
Plasmonics
Our research is focused on the development and understanding of plasmon-based systems capable of producing chemicals (artificial photosynthesis and photo-redox catalysis), electricity, and other cool stuff with light.
Spin-out for transparent plasmonic solar cells
Jacinto Sá is the founder of Duck Technologies AB, a spin-out company that is developing a highly transparent coatings to address overheating problem in buildings, vehicles and photovoltaics.
