Dr. Panagiotopoulou Margaritareceived her degree in Chemical Engineering and her PhD in Nanoencapsulation of bioactive compounds in natural polymer matrices from the School of Chemical Engineering of the National Technical University of Athens. Her research work focuses on: physical processes (Air, Spray and Freeze drying), micro and nanoencapsulation (Electrospinning-Electrospraying methods), physicochemical characterization of polymers, recovery of bioactive compounds derived from agricultural and food waste through different extraction techniques, valorization of these compounds for the creation of value-added products etc. She currently works as a Postdoctoral Researcher at the Institute of Nanoscience and Nanotechnology of NCSRD and her activity focuses on the materials and process development for the production of passive radiative cooling films for solar cells. More specifically, Dr. Panagiotopoulou currently works on the MultiCool project “Hybrid, multifunctional cooling metamaterials for next-generation high-efficiency solar cells”. Her research focuses on the creation of composite films based on thermoplastic polymers and UV curable resins containing micro and nano particles of silicon dioxide (SiO₂) and titanium dioxide (TiO₂) for passive radiative cooling in solar panels. Her work includes the formation of the hybrid materials, the application of thermal and UV Nanoimprint lithography (NIL) for the patterning of the films and their morphological and spectral optical characterization
