'Messy' Production of Perovskite Boosts Solar Cell Efficiency

Visualisation of how the charge carriers (in purple) accumulate in the disordered perovskite structures.

Scientists at the University of Cambridge studying perovskite materials for next generation solar cells and flexible LEDs have discovered that they can be more efficient when their chemical compositions are less ordered, vastly simplifying production processes and lowering cost. The surprising findings,

Machine Learning Enhances Light-Beam Performance

This chart shows how vertical beam-size stability greatly improves when a neural network is implemented during Advanced Light Source operations. When the so-called "feed-forward" correction is implemented, the fluctuations in the vertical beam size are stabilized down to the sub-percent level (see yellow-highlighted section) from levels that otherwise range to several percent.

Synchrotron light sources are powerful facilities that produce light in a variety of "colors," or wavelengths - from the infrared to X-rays - by accelerating electrons to emit light in controlled beams. Synchrotrons like the Advanced Light Source at the Department of Energy's Lawrence Berkeley
