A new study, published in Nature Nanotechnology and featured on the journal’s front cover this month, has uncovered insights into the tiny structures that could take solar energy to the next level.

Researchers have achieved a new level of control over the atomic structure of a family of materials known as halide perovskites, creating a finely tuned ‘energy sandwich’ that could transform how solar cells, LEDs and lasers are made.

Halide perovskites – already a focus of major research in the department into efficient, low-cost solar cells – have been shown to handle light faster than most semiconductors on the market.
