Maria Antonietta Loi

Maria Antonietta Loi (born 4 May 1973) is an Italian physicist who is a Professor of Optoelectronics at the University of Groningen and member of the Zernike Institute for Advanced Materials. Her research considers the development of functional materials for low-cost, high efficiency optoelectronic device. She was awarded the 2018 Netherlands Physical Society Physics prize (Physicaprijs). In 2020, she was elected Fellow of the American Physical Society. In 2022 she became a fellow of the Dutch academy of science (KNAW) and of the European academy of Science (EurASc). Loi is Deputy Editor-in-chief of Applied Physics Letters.

Loi was born in Quartu Sant'Elena, Sardinia. She studied physics at the University of Cagliari. She was awarded honours for her undergraduate degree in 1997, before embarking upon a doctoral research program. After earning her PhD she moved to the Johannes Kepler University Linz, where she worked as a postdoctoral researcher on organic solar cells. After one year in Austria she returned to Italy, where she joined the Italian National Research Council Institute for Nanostructured Materials.

In 2006, Loi was appointed Assistant Professor at the University of Groningen, and awarded a Rosalind Franklin Fellowship. Her early work considered the investigation of organic semiconductors and carbon nanotubes photophysical and optoelectronic properties. She was made Chair of the Department of Photophyics and OptoElectronics in 2011, and Full Professor in 2014.

Loi's research considers the development of solution processable semiconductors and hybrid nanomaterials. In particular, she has explored perovskites for solar cells and X-ray detectors. She has shown that Sn-based perovskites have intriguing physical properties such as showing photoluminescence from hot-carriers with long lifetimes.
