we see a clear trend: lattice engineering enables 2D-templated FAPI to exhibit superior carrier extraction and transport with reduced non-radiative recombination losses compared to MACl-stabilized FAPI, highlighting its enhanced stability. Thanks to @ANRFIndia @IndiaDST @jncasr.

The improved performance and stability lattice-engineered-2D-templated FAPI-based solar cells were attributed to the microstructural aspects of strain-relaxed α-FAPbI3 formation. Further, the response parameters in these studies also serve as a tracker to follow the degradation,.

We observed that marginal improvements in solar cell parameters upon structural process modifications are magnified in the transient dynamic and frequency domain measurements, and demonstrate its utility as a yardstick for structure-property correlation.

Our new paper comes up with an insight into the performance and stability aspects of structurally engineered hybrid perovskite cells, is out spearheaded by graduate student @Chandan56876984, Great collaboration with @MPEMRice Aditya Mohite group.

Time-resolved emission unveils detailed transition dynamics. These findings show a promising avenue for further exploration in the realm of light- matter interaction between molecules and cavities, with potential implications for advancements in OLED and organic laser application.

We observed significant splitting of the lower hybrid state leading to a modulation in decay rates, It showcased an average reduction in the lifetime of about 10 μs and a remarkable decrease in full width at half maximum by over a factor of three.

A tuning of the cavity modes is required to align with the molecular exciton range. This handle of incident and collection angles (rather than film thickness) is more useful to fine-tune the photon-exciton coupling regime. We carefully carry out this angle dependent measurements.

A promising approach for simultaneously maintaining high oscillator strength and low ΔEST is use of exciton-photon coupling-induced hybrid states. large dipole moment and high binding energy of the Frenkel exciton in TADF molecules make them suitable for strong coupling regime.

via a reverse intersystem crossing RISC. The efficiency of the RISC process requires a minimization of the energy gap (ΔEST) between the first excited triplet state (𝑇1) and the first excited singlet state (𝑆1).

Our new paper is out. Led by Sinay @beherasinay and @Anaranyaghorai, this is a nice example of benchtop Molecular Quantum-mech. Summary: TADA Molecules are normally designed to have suitable emissive singlet levels, & also accessible by a triplet level.

End (beginning) of an era. Academic paper producing machine !?

Wonderful thread, need of the hour for many of us. going through cognitive overload.
