🌞 SOLAR: A Midwest collaboration has resulted in a new smart window that could generate energy while also adjusting to the user’s preferences.
Scientists at Argonne National Laboratory, Northwestern University, the University of Chicago and University of Wisconsin-Milwaukee contributed to the design, which uses solar cell technology to convert sunlight to electricity. The project aimed to balance energy capture with design — a challenge for previous smart windows.
- The prototype is made from dozens of layers of materials, including perovskite and a nanophotonic coating that control the amount and frequency of light that is allowed to pass through. It also controls the amount of solar energy converted to electricity.
- The prototype optimizes design to overcome difficulties in other smart window models, namely balancing indoor light preferences, building temperature, and energy harvesting goals across seasonal changes.
- “Rather than focusing only on the amount of electricity produced by the solar cell, we consider the entire building’s energy consumption to see how we can best use solar energy to minimize it,” Wei Chen, an engineering professor at Northwestern, said in a news release. “Additionally, the sunlight that doesn’t pass through is captured by the solar cell in the smart window and converted into electricity.”
- Future work could involve making a flexible smart window that could be retrofitted to cover existing traditional windows.
🔋 ENERGY STORAGE: The U.S. Department of Energy is seeking input on the newly released Energy Storage Grand Challenge Draft Roadmap. The roadmap outlines a strategy to accelerate energy storage technology development.
