Uncovering the secrets of super solar power perovskites
The best hope for cheap, super-efficient solar power is a remarkable family of crystalline materials called hybrid perovskites. In just five years of development, hybrid perovskite solar cells have attained ...
Scientists move closer to 'two for one deal' on solar cell efficiency
The underlying mechanism behind an enigmatic process called "singlet exciton fission", which could enable the development of significantly more powerful solar cells, has been identified by scientists in a new study.
Nano-device used to create and control rogue optical waves
A tiny chip, developed by scientists at the University of St Andrews, could help aid understanding into how rare events such as rogue waves occur.
