Bio

Dr. Sudip Kumar Batabyal is the Senior Research Scientist in ACIRI. Prior to joining ACIRI in 2015, Sudip has over 8 years of research experience in nanomaterials fabrication and application in renewable energy sector. His areas of expertise and research interests include semiconducting nanomaterials for energy harvesting and storage, perovskite materials, printed electronics, and energy storage. Sudip received his M.Sc in Physics from Vinoba Bhave University and Ph.D from Indian Association for the Cultivation of Science ( Jadavpur University).

Sudip worked in National University of Singapore on metal coordinated gel and co-ordination polymeric nanofiber from 2007 to 2010. After that he shifted to Energy Research Institute @ Nanyang Technological University (ERI@N) and started work on the project of solution processed Cu2InGa(S/Se)2 (CIGS) and Cu2SnZn(S/Se)4 solar cell. He developed the CIGS and CZTS absorber layer deposition on Mo substrate by spray pyrolysis method. He successfully fabricated the solution processed CIGS device with more than 10% efficiency.

In his research career, he has focused on a wide variety of novel materials (metal chalcogenide, metal oxide, organic semiconductors, carbon nanotubes and graphene) synthesised by a range of fabrication procedures. His main emphasis was on the electronic and optical properties of these materials and direct application of these nanostructures in practical devices. His primary research interests are photovoltaics, photoelectrochemical systems and energy storage. His research work has been published (~80 publications) in many high impact factor journals such as Nature Communication, Advanced Materials, ACS Nano and Advanced Energy Materials etc.

Doctoral research work

  • 2001-2005: Indian Association for the Cultivation of Science, Kolkata, India on synthesis and characterization of some novel nanomaterials under the guidance of Prof.Chitra Basu since March 2001.

Postdoctoral Research work

  1. 2006-2010: National University of Singapore under the supervision of Prof. J. J. Vittal from 2006 to 2009 on semiconducting nanomaterials and metal co-ordinated polymeric nanofiber (metalo gel).
  2. 2010-2015: Working as a senior scientist in the Energy Research Institute @NTU, Nanyang Technological University on thinfilm photovoltaic devices. I supervised the group activity of CIGS group. We developed some solution phase fabrication technique of CIGS solar cell for economic and large scale production. Along with the CIGS and CZTS type devices, I also worked on the other p-n junction photovoltaics devices and DSSC. We developed different metal sulfide and oxide composite nanostructures and use them for solar water splitting and for energy storage in Li and Na ion battery.

Research Interest

Solution Processed PhotovoltaicSolution Processed Photovoltaic Device Device: High fabrication cost of solar cell is the main obstacle for the wide spread application of the solar energy harvesting. Our aim is to develop simple cost effective technology for the fabrication of high efficient solar cell from solution chemistry. We are mainly focused on the thin film PV devices and third generation solar cell.

Nano materials for energy hNano materials for energy harvestingarvesting: Our Main emphasis is on the synthesis and application semiconducting nanomaterials for energy harvesting. Because of size dependent properties we can tune the band gap of the materials and can synthesised selective band gap materials for device application. Also we are interested to modify the surface chemistry of the nanomaterials for the selective application.

Materials developmMaterials development for solar water splittingent for solar water splitting: We are interested for conversion of the solar energy into chemical fuels (H2) by photocatalytic reactions and conversion of the greenhouse gas CO 2 into hydrocarbons fuels via photocatalytic reactions. Our main focus is to development of electrode materials for photoelectrochemical energy harvesting by understanding the electronic properties of the materials such as carrier concentration, mobility, trap density, carrier diffusion length and interaction with the electrolyte

Electro ChemicalElectro Chemical Energy storage Energy storage: Energy storage devices and systems have an important role in realizing the renewable energy future for our society. So to spread the application of renewable energy we have to develop cost effective energy storage devices. We are interested on the development of low-cost, nanostructured materials and composite materials for high-performance electrode for electrochemical energy storage systems. The synthetic methodology will be environmentally friendly and compatible with large-scale processing for energy storage systems including lithium, sodium batteries and electrochemical capacitors.
