How Bulky Molecules Improve Next-Generation Solar Cells

Adding “bulky” organic molecules earlier in solar-film synthesis slows crystal growth, leading to the formation of a protective surface layer that improves durability and efficiency. These next-gen materials could revolutionize solar-cell technology, offering increased efficiency, lower cost, lighter weight, and flexible solar modules. Read more »PPT-icon-35 PDF-icon-35

ATLAS Masterclass Visits the ALS

In late April, the Berkeley Lab Physics Division hosted an ATLAS masterclass for high school students where they could learn about high energy and particle physics and analyze real data from the ATLAS detector at the LHC at CERN. For on-site participants, the day included a tour of the ALS. Read more »

September Call for 2023 and 2024 Publications

All publications resulting from work done in whole, or in part, at the ALS must be recorded by the User Office for the Department of Energy (DOE). Please help ensure our records are complete by reporting your ALS publications, especially those published in 2023 and 2024. Read more »

Probing the Liquid/Vapor Interface of a Tunable Solvent

Despite the ready tunability and industrial promise of deep eutectic solvents (DESs), there have been few x-ray spectroscopy studies at their liquid/vapor interfaces—which is relevant for their use in applications such as greenhouse-gas capture. Here, researchers probed the liquid/vapor interface of a benchmark DES using complementary spectroscopies. Read more »
