Sutripto Majumder

   At present, I have been hired as the International Research Professor (Assistant Professor) at Yeungnam University, Gyeongsan, South Korea. Before this, I was gaining my research experience as a postdoctoral fellow at Chungnam National University, Daejeon, South Korea.  I received PhD degree (Sep-2017) from Visvesvaraya National Institute of Technology (VNIT), an “Institute of National Importance” in Nagpur India. Masters in Physics (2006) from Department of Physics, Rani Durgavati University whereas Bachelor's degree in Electronics (2004) from Sri Guru Teg Bahadur Khalsa College affiliated to Rani Durgavati University, Jabalpur, Madhya Pradesh, India.

      My current research focuses on the work and experience gain in the field of photoelectrochemical water splitting and perovskite materials for photodetection. In my Post-doctoral tenure, I have worked on the vivid areas of the photoelectrochemical water splitting photodetectors and gas sensors. Emphasis has been made on the synthesis of the metal oxide/chalcogenides as binary or ternary materials which can be coated over the popular metal oxides (such as BiVO4, Fe2O3, SnO2, WO3, ZnO, TiO2, etc.), in order to enhance the overall photoelectrochemical performance of the basic material. New methods of formation of these binary or ternary materials, when coated over the base material, is my prime intention. Actually, here the well-known popular materials have their own characteristic features that act as a constraint to their own photoelectrochemical performance. The deposition of these newly made innovative materials (in an easy and cost-effective way) may coat over the base materials to form heterojunction, or as a photocatalyst were both in the form of amorphous and crystalline phases quite helpful to produce oxygen or hydrogen through water splitting.

      Apart from this as a Post-doctoral, I was also an active member of the group working for the development of the perovskite material for the application of photodetectors. The optimization of the CVD-made basic perovskite (i.e MAPbI3-xClx ) is comparatively high stable and reproducible in terms of performance than the other wet chemical synthesis.  As the output of the studies, I am intrigued to find that CVD coated MAPbI3-xClx displays self-powered photodetectors with good operating stability for next-generation optoelectronic systems and their applications.

       I was also engaged to conceptualize different nanostructured materials over the alumina substrate for the application of the Gas-sensors. I worked on designing different nanosized metal oxide materials to anchor Carbon Nano Tube CNT developed through the arc-discharge method. From an application point of view, stress has been applied over the detection of the different volatile gases that have been made at room temperature, with the concerns of humidity effect.     

        During my Doctoral studies, I have worked on the design and development of metal Chalcogenides (i.e. CdS, CdSe, PbS) to form nanostructured sensitized solar cells. Briefly, I found how the different nanostructured materials (i.e. CdSe and PbS) behave when decorated over the well-optimized CdS nanowires that enhance the photoelectrochemical solar cell performances. This led me to materialize the concept of the formation of the lab-grade liquid solar cells with enhanced power conversion efficiency through the core-shell heterojunction. Furthermore, I have hands-on over Dye-Sensitized Solar Cells, Quantum Dot Sensitized Solar Cells, Organic Solar Cells, and even Solid-state Polymer solar cells. Within that period of time, I have developed a keen interest in the fabrication of the different nanostructured thin films for the purpose of Asymmetric and Symmetric Supercapacitors
