The PON NAUSICA project aims to implement advanced technologies for efficiency and intelligent management of vessels reducing the environmental impact of fleets and decrease the operating costs of operators in the maritime transport sector. In particular, CNR-IPCF Messina activities are focused on the development and demonstration of advanced materials, devices and innovative technologies for the production and storage of energy from renewable sources in order to achieve a progressive decarbonisation of the energy system on-board and to improve environmental sustainability. The goal is to demonstrate on-board prototypes on an appropriate scale, capable of operating both in outdoor and indoor conditions with diffused light, with conversion efficiencies close to 10% e with an integrated storage system. Solid-state and flexible devices belonging to dye sensitized solar cells (DSSC) will be developed in collaboration with ISMN Palermo and other partners to also achieve high performance in underwater systems.
