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. ⚡

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...

RASEI @rasei.bsky.social · Sep 16

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.

RASEI @rasei.bsky.social · Sep 16

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.

RASEI @rasei.bsky.social · Sep 16

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.

RASEI @rasei.bsky.social · Sep 16

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.

RASEI @rasei.bsky.social · Sep 16

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...
