Our latest work from the lab investigating the subcell charge carrier dynamics in perovskite/Si tandem solar cells using transient photocurrent spectroscopy. Thanks to Suhas and Prof. Snaith for providing us with the high efficiency tandem cells and Prashant for valuable insights

We are back! Our Perovskite/Silicon Tandem Solar Cells entered the NREL chart with a certified efficiency of 32.5% Thanks to all the amazing people contributing to this achievement. Silicon Solar Cells Group @HZB Helmholtz-Zentrum Berlin

Thanks a lot sir for your guidance and suggestions in exploring the various topics in my PhD.

Time for sharing 3 stories from the lab. 1st one from PhD student Sinay’s persistent efforts that led to an interesting obs, appearing in advanced optical materials “the triplet state dynamics of organic phosphorescent molecules are affected by their environment (host matrix)”.

The 2nd recent paper is on transient electroluminescence method to study OLEDs by Anaranya who just got his PhD and moving to Georgia State, USA. OLEDs can be > 25%efficient-singlet quantum yield limit. In the phenomena of delayed emission,the lossy triplets channels is harnessed

The third in the series is from Sumukh the electronics expert in our lab. Printed electronics- a rapidly growing field with possibility of large-scale manufacturing of polymer-based LED displays & Imaging Devices. An integrated combination of these components is fabricated

How do conducting polymer blends get organized in rigid-confined-nanopores ? Find out in our recent paper led by Sukanya Das pubs.rsc.org/en/content/art… We correlate enhanced electrical features to structural aspects, thanks to Sarbani G & Pranay- BITS (P) for MD simulation insight

Excited to start another yr at GSU chem, & our group is growing. Anaranya Ghorai joined as a postdoc & Gauri Tripathi joined as a grad student. We have opening for more grad students for Spring/Fall 2024 to work on ultrafast spectroscopy. Please RT. #Chemtwitter #AcademicChatter

Structured hybrid photodetectors using confined conducting polymer nanochannels - now published in Nanoscale Advances pubs.rsc.org/en/content/art… These findings deal with hybrid (perovskite) photodetector device made of conducting polymer blends confined in nanochannels.

our journey of exploring polymer semiconductors as prosthetic elements to address retinal disorder of retinitis pigmentosa & macular degeneration (AMD) over a decade continues, Investigations on artificially extending the spectral range of natural vision pubs.aip.org/aip/apb/articl…

I am recruiting grad students Georgia State University Chemistry to work on exciting materials chemistry projects using linear and nonlinear spectroscopy. Please RT! Students are highly encouraged to email me ([email protected]). (1/)#chemtwitter #chemphd #AcademicTwitter #AcademicChatter

End of the year update, Sinay Behera Sinay Simanta Behera comes with interesting studies on light emission from color-centers in Nanodiamond (NDs) coated on spontaneously patterned polymer-photonic structure SERB DSTIndia, appearing in Optics Letters,opg.optica.org/ol/upcoming.cfm

Excited to share the first research article from our lab on “Variable Non-Gaussian Transport of Nanoplastic on Supported Lipid Bilayers in Saline Conditions.” Congratulations to all authors, and thanks to Atanu Acharya lab for providing MD insights. pubs.acs.org/doi/10.1021/ac…

Months of relentless hard work finally paid off, we built the VSFG setup in our lab. Time for some coherent surface spectroscopy!!! Anaranya Ghorai GSU Arts & Sciences Georgia State University Research Georgia State University Chemistry

Our recent mini review on vibrational sum frequency generation spectroscopy

We are ready for sermacs2024 happening next week here in Atlanta. We will be there with two talks (Anaranya Ghorai , Diyali Sil ), two posters (Gauri Tripathi , sydney, edin), and a full symposium. Please stop by if you are attending SERMACS. GSU Arts & Sciences Georgia State University Chemistry
