Our recent J. Am. Chem. Soc. represents first example of water-stable 2D hybrid halide compound with ideal 180° Pb−I−Pb bond angle leading to very small bandgap, exciton binding energy and improved PV performance doi.org/10.1021/jacs.3… Debasmita Pariari, Abhishek Mondal's Group and other authors.

Please check out our recent work in J. Am. Chem. Soc.. The angle matters!😀D. D. Sarma's Group #Bandgap #Exciton #BindingEnergy #LeadHalide #Perovskite doi.org/10.1021/jacs.3…

How do we lower thermal conductivity even below the minimum? Spin the dipoles faster! Check out our recent ACSEnergyLett article. Congratulations to the authors! Debasmita Pariari Paribesh Acharyya Shaili Sett Kanishka Biswas Umesh V Waghmare Arindam Ghosh doi.org/10.1021/acsene…

Check out our ACSEnergyLett article on "Non-monotonic Thermal Conductivity of FAxMA1−xPbI3" where we explore how the organic cations influence thermal conductivity in the series. D. D. Sarma's Group #Perovskite #LeadHalide doi.org/10.1021/acsene…

"Unraveling low-temperature structural and dielectric characteristics of lead free bismuth halide perovskites" by  soumitrasatapathi  and the team has recently appeared in the J. Mater. Chem. family C. Congratulations to all the authors. Here is a link to the article doi.org/10.1039/D4TC03…

We are delighted to announce that D. D. Sarma (DD) has received  R.D. Birla Memorial Award for the year 2024 from the Indian Physics Association for his pioneering contributions to material physics. For past recipients, visit this link. tifr.res.in/~ipa1970/rdlis…

Glad to be a part of the team!

Check out our recent article in ACSEnergyLett on how the NiO sputtered perovskite solar cells heals automatically without any external intervention. Congratulations to Debasmita Pariari for her contribution to this collaborative venture. doi.org/10.1021/acsene…

Check out our Chemistry of Materials article where we uncover an intriguing ultralow thermal conductivity in a crystalline material TlCuZrSe3 which approaches its theoretical limit of minimum thermal conductivity. Congrats to ROHIT ROHJ and other authors. doi.org/10.1021/acs.ch…

Finally this is published. Glad to be a part of this project.

Check out our recent article published in Energy & Fuels special issue “2025 Pioneers in Energy Research: Prashant Kamat” where we reported a new series of 2D hybrid halide passivators. Congrats to Debasmita Pariari & other authors. doi.org/10.1021/acs.en…
