I (Dr. Shubhranshu Bhandari) am an Assistant Professor at the Institute of Physical Chemistry, Polish Academy of Sciences, where I currently conduct advanced research and have been awarded the prestigious MSCA-BS4S Fellowship. I previously served as a Postdoctoral Researcher within the Faculty of Environment, Science and Economy at the University of Exeter, the same institution where I earned my Doctor of Philosophy (PhD) degree. My research focuses primarily on advanced materials science and the development of next-generation sustainable energy technologies. I have co-authored numerous peer-reviewed studies focused on perovskite solar cells (PSCs), Nanomaterials and thin films, 2D materials, and building-integrated photovoltaics (BIPV) for modern architectural applications. In addition to my primary research, I actively contribute to the broader scientific community, having served as a Guest Editor for a specialised academic journal (Sustainability, MDPI) focusing on advancements in solar cell technologies.
