City without walls: Buildings, energy, psychology overlap, says researcher
2024-03-04 14:42:38
Although he built his career around buildings, Fengqi "Frank" Li likes to break down walls. Li was trained as an architect, but he doesn't box himself in. Currently he is working as a computational developer at the Department of Energy's Oak Ridge National Laboratory. But Li considers himself a designer. To him, that's less a box than a plane—a landscape scattered with ideas, like destinations on a map that can be connected in different ways.

Guiding future research on 'extraordinary potential' of next-generation solar cells
2024-02-29 23:33:01
Today's commercial solar panels can convert about 15% to 20% of the sunlight they absorb into electrical energy—but they could be much more efficient, according to researchers at Soochow University. The next generation of solar cells has already demonstrated 26.1% efficiency, they said, but more specific research directions are needed to make such efficiency the standard and expand beyond it.
Researchers improve the stability of perovskite solar cells
2024-02-29 23:33:01
Perovskite solar cells are thought of as the strongest contender to replace conventional silicon solar cells in next-generation photovoltaics. They are made of an A+ cation, a B2+ divalent cation, and an X- halide. Generally containing Pb2+ or Sn2+, they achieve high power conversion energy that is suitable for commercial use.
