M. Bag's Group at IIT Roorkee...
We are mainly working on inorganic-organic hybrid perovskite materials; towards improving the efficiencies of perovskite LEDs and perovskite solar cells.
Zahner impedance spectroscopy setup is used to study the energetics at various interfaces, understanding the band structure of materials.
Our purpose is to achive balanced charge injection and reduced leackage current at the interface. Our group is working towards the optimization of morphology of thin films prepared by solution processed coating technique.
Any noise could be unwanted for common people but is important for us to understand optoelectronics devices. Like any other spectroscopic technique, Noise spectroscopy can unfold significant insight about charge transport properties in the devices. Along with Electrochemical Impedance Spectroscopy (EIS) and Intensity Modulated Photocurrent/Photovoltage Spectroscopy (IMPS/IMVS), our group focus on the Noise spectroscopy as alternative tool to understand charge carrier dynamics in various optoelectronics devices.
P. Srivastava and M. Bag have contributed the book chapter " Chapter 5: Ion Transport and Stability Issues in Perovskite Materials " for the book " Revolution of Perovskite - Synthesis, Properties and Applications ".
This laboratory along with LINB, Space Physics and Energy Storage Laboratory have much bigger place, with semi-clean room facilities equiped with state-of-the-art instruments.
The 2018 MRS Fall Meeting and Exhibit was held in Boston, Massachusetts, November 25-30, 2018. The 2018 MRS Fall Meeting & Exhibit is the key forum to present research to an interdisciplinary and international audience.
Priya published her first article titled as Temperature Assisted Nucleation and Growth To Optimize Perovskite Morphology at Liquid Interface: A Study by Electrochemical Impedance Spectroscopy
