Principal Investigator

Juan-Pablo Correa-Baena, PhD

Assistant Professor


Juan-Pablo Correa-Baena an Assistant Professor and the Goizueta Junior Faculty Rotating Chair in the School of Materials Science and Engineering at the Georgia Institute of Technology in Atlanta, USA. His group focuses on the understanding and control of electronic dynamics at the nanoscale of low-cost semiconductors, such as halide perovskites and other materials, for optoelectronic applications. Juan-Pablo’s group works on advanced deposition techniques, with emphasis on low-cost equipment and high throughput, as well as advanced characterization methods that include synchrotron-based mapping and imaging approaches with nanoscale resolution 

 

Juan-Pablo received his PhD from the University of Connecticut, where he studied metal oxide aerogels as porous conductive electrodes for dye-sensitized solar cells, funded by two National Science Foundation fellowships. His work as a postdoctoral fellow in the group of Prof. Anders Hagfeldt at the Ecole Polytechnique Federale de Lausanne focused on understanding the role of band offsets at interfaces in perovskite solar cells. He was awarded a Department of Energy EERE fellowship to conduct work at MIT, where he helped shed light onto minority phase formation and elemental distribution in complex, multi-element halide perovskites.

Carlo Perini

Postdoctoral Researcher

Carlo’s current interest is developing and understanding 2D electronic passivation of 3D perovskites via vapor-based deposition routes, target field of application being photovoltaics. Carlo has a Ph.D. in Physics (2019 – Politecnico di Milano), obtained in collaboration with the Italian Institute of Technology (IIT), where he studied and developed new low temperature solution deposition routes for Nanotechnology at Politecnico di Milano, with a thesis on bulk-heterojunction organic solar cells for indoor applications. Through a collaboration with the start-up RibesTech, he investigated the relationship between solvent choice, polymer-blend morphology, and power conversion efficiency of complete organic solar cells.
