Supply-chain delays, rising equipment prices threaten electricity grid The equipment needed to keep the grid running is hard to make, and materials are limited. And supply-chain bottlenecks are taking years to clear.

This great article, co-authored by RASEI Fellow Kyri Baker in The Conversation, is out today and explores how rising equipment prices and delays in supply-chains impact and threaten the U.S. Power Grid.

New ‘Molecular Dam’ Stops Energy Leaks in Nanocrystals October 2025

7/ Check out our highlight here: www.colorado.edu/rasei/2025/1...

6/ 📖 Read the full study in Chem: doi.org/10.1016/j.ch...

5/ Imagine a future where plastics and pharmaceuticals are made using light—not fossil fuels. This research is a step toward that vision. 🌍💡

4/ The work is part of the DOE-funded Energy Frontier Research Center: Ensembles of Photosynthetic Nanoreactors (EPN), bringing together experts across institutions. 🧪🤝: photosynthesis.uci.edu

3/ This extends the lifetime of the charge-separated state to microseconds—a huge leap in photochemical timescales! 🕒

2/ The innovation uses a molecule that binds tightly to the nanocrystal surface and shuttles away positive charges (holes), preventing energy loss from recombination. ⚡

1/ 🚨 Big news in photochemistry! A team led by RASEI's Gordana Dukovic has created a molecular dam that slows energy leaks in nanocrystals—making light-driven reactions 40x more efficient! 🌞🔬

2025 Nozik Lecture November 2025

Understanding how these films degrade is critical in developing approaches to prevent decomposition in future designs. We can’t stop shade and shadows, but through careful scientific investigation we can create designs that can handle it: www.colorado.edu/ras...

This suite of tools enabled the team to identify pinholes and weak spots in the perovskite films that were the sites of the reverse bias decomposition, providing direct evidence for the mode of decomposition.

The exact mechanisms of how this decomposition happened were unknown and were the subject of debate. This study from the McGehee group used a suite of advanced techniques to examine the perovskite layer before and after reverse bias.

Like the water in a kinked hose that will eventually burst at the weak point, current in a solar cell in reverse bias will find the weak point and cause an electrical short, causing heat, damage, and significantly reducing performance.

When solar panels, or parts of solar panels, are in the shade, they are exposed to reverse bias, charge is pushed through even though the panel is not generating electrons. Think about it like trying to push water through a kinked hose.

Just out from RASEI Fellow Mike McGehee, a new study that directly addresses one of the key issues associated with perovskite-based solar cells: how perovskite films decompose when they operate in the shade: www.colorado.edu/ras...

Affordability, Not Volatility: Renewables' Cost Advantage Grows - RMI Recent reports show that renewables are resoundingly cost-competitive.

This interesting insight from RMI shows with a single figure shows how renewables vs fossil has changed in the last 10 years. >90% of renewable projects are cheaper to build. Affordability is going to be a central driving force to move to renewable-plus-storage: rmi.org/affordabilit...

The 89% project: tell us why climate action matters to you We’d like to hear why you care about the climate, and whether anyone has inspired you to take action

The majority of people want more to be done about the climate crisis. This interesting project is asking for feedback from the population about why they care. Pass it along!
