New paper went online on my bday! Thank you @NatureEnergyJnl for the bday gift 🎁 Ultrathin, lightweight #perovskite #solarcells with improved stability powering palm-size Solar Hopper quadcopter drone https://t.co/4g7N1rRoGY

In this work we show that UV light can be used to control how perovskite crystals form: depending on the composition, UV exposure either suppresses crystallization (in 3D perovskites) or promotes it (in 2D perovskites), enabling crystal growth under mild conditions.

Happy to share that our paper “Photochemical Control of Perovskite Crystal Formation at Room Temperature” is now published in Advanced Science!

Feel free to check it out! https://t.co/NAPpc2jHDf

This photochemical lever offers a simple, low-energy method to steer perovskite film formation, which could open up new routes for flexible films, composite materials, or novel device architectures.

@joeltroughton @undalogic that looks awesome! always wanted to have a compact SMU. thanks for developing this and keeping all things open-source

[Steve Albrecht's Lab @AlbrechtLab]

We investigated the effect of different anions for piperazinium salts. We found and explained an anticorrelation of stability and efficiency (1.68 eV bandgap perovskite)

Good balance for PTsO with 96.4% of initial efficiency after 1000h ISOS-LC-1I

@nihar_gupte as someone from a very different field of science, I just want to say that I really like the design of your poster! and also thanks for sharing a nice explanation for someone not familiar with the topic! great work!

[Stepan Demchyshyn @Stepan_Demch]

@YolandaSalSol congratulations!
