INVERT

About the project

Inverters are essential for renewable energy-based distributed electrical grids where, for example, they convert DC power generated by solar panels into AC power used by household appliances. But the hundreds of capacitors inside every inverters make them bulky, which often makes the renewable energy options space inefficient and unattractive compared to diesel generators. This project therefore aims to understand more about a new, more energy-dense capacitor material: antiferroelectrics. Due to the antiferroelectric polarization-electric field response, these materials can have a large recoverable energy storage potential. This project aims to stabilize the antiferroelectric properties of NaNbO₃ via microstructure tailoring to keep the antiferroelectric-ferroelectric transition reversible. The project is a collaboration with Technische Universität Graz.
