Defects may be inevitable in metal halide perovskites, but controlling them is transformative. Our latest review highlights how defects govern device performance in solar cells & LEDs. @IITKanpur @ANRFIndia @ACSEnergyLett https://t.co/DyzQdBe6De

[Vishal Govind Rao @VishalGovindRao]

What does it take to make halide perovskites actually work as photocatalysts?
We connect stability, solvent effects, and surface charge engineering into a unified design framework.
Thanks to @IITKanpur and @ANRFIndia for the support.

@Manoj_IITK @DaltonTrans @mofesmml @jncasr @Srinivas_IITK Congratulations, Manoj!!

[Shivani Gupta @Shivanig22]

@BidhanKumbhaka2 Thanks Bidhan

[Shivani Gupta @Shivanig22]

Thank you, Sir!!

[Vishal Govind Rao @VishalGovindRao]

Congratulation to Shivani Gupta, for leading a deep dive into how surface termination and A-site chemistry truly govern charge transfer in perovskite photocatalysts. From careful experiments to sharp mechanistic insight, this paper carries her imprint throughout.

Our new paper shows how interface chemistry acts as a gatekeeper for efficient charge transfer in perovskite photocatalysts, enabling improved solar-driven reactions. 🔆 @ACS_AEM Thanks to @IITKanpur @ANRFIndia

Monika Ahlawat, Siddharth Singh, and Pooja Aggarwal....we will always miss you!!

[Vishal Govind Rao @VishalGovindRao]

This collage captures our journey — how a small group grew together, laughed together, and became a family.
Today, we bid farewell to the one who made every moment brighter.
Siddharth, your next chapter will be extraordinary, because you are.
Wishing you limitless success.

Can a tiny water droplet decide the fate of excitons? 💧
Yes! Reverse micelles let us tune charge vs. energy transfer in CsPbBr3-Rhodamine systems-making FRET shine bright for light-harvesting innovation. @IITKanpur https://t.co/wxvBcrVCtZ

[Vishal Govind Rao @VishalGovindRao]

New insights on perovskite nanocrystals! Our latest paper shows how tuning OAmBr ligand density in CsPbBr3 NCs enhances charge transfer & stability for solar cells. CPB12 hits 10x higher efficiency! Curious? Dive into the science! @IITKanpur @ANRFIndia

Shivani's double strike in her first three years: Small ✅ ACS AMI ✅
And with that—Party time! 🎉🎂
We totally don’t have an unspoken lab rule about first authors giving treats after every two papers… 😇
Kanpur economy rejoices, our wallets don’t. #LabLife #PhDChronicles

@ArghyaS18897681 Thanks, Arghya bhaiya!!

[Shivani Gupta @Shivanig22]

Thank you, Sir!!

[Vishal Govind Rao @VishalGovindRao]

This work would not have been possible without my brilliant PhD student Shivani Gupta and master’s student Harsh Patel.
From synthesis to spectroscopy, your dedication made this advance possible.
A molecule that accepts holes & impedes phase segregation, who would've thought! 🔥

[Shivani Gupta @Shivanig22]

@AOtuebe Thanks, AOtuebe!!

[Shivani Gupta @Shivanig22]

@nitinsharma_07 Thanks, Nitin Bhaiya!! 😊

[Shivani Gupta @Shivanig22]

Wait is over!! Check this out!!

[Vishal Govind Rao @VishalGovindRao]

📣 Just out in Small (Wiley)! @WileyGlobal
Phase segregation in mixed-halide perovskites is a well-known challenge—but what if we could steer holes away from iodide and halt phase instability at its root?
We do exactly that👇 @IITKanpur

@GangulyDebarjya Thanks, Debo!! 💙

[Vishal Govind Rao @VishalGovindRao]

Using Ferrocene-based molecules as directional hole acceptors + dual defect passivation, we suppress iodide oxidation and expulsion from nanocrystals.
📉 Less spectral shift
☀️ More photostability
🧪 Surface chemistry = game changer
Thanks to @ANRFIndia for the support.

[Shivani Gupta @Shivanig22]

@ArghyaS18897681 @Chemistry_IITK @IITKanpur Congratulations Bhaiya

🌍 Sunlight + Halide Perovskites = Green Chemistry Revolution?
Our @AdvMater review unpacks how these rising stars can drive clean fuels & organic synthesis—and what hurdles lie ahead.
A must-read for the future of sustainable photocatalysis! https://t.co/b6IYLjeEJi
