In a world hungry for cheaper, more efficient renewable energy, Australian researchers have served up a treat.
Work led by the ARC Centre of Excellence in Exciton Science has shown that the two-dimensional (2D) thin films used in some perovskite solar cells closely resemble a sandwich. Perovskite is an exciting material at the forefront of solar energy research and design.
Previously, scientists thought these 2D perovskite films had a ‘gradient’ structure, in which certain components were found deep in the material, with other complementary elements only located nearer to the surface, like topping on a cracker.

- 30Researchers in the materials department in UC Santa Barbara's College of Engineering have uncovered a major cause of limitations to efficiency in a new generation of solar cells. Various possible defects in the lattice of what are known as hybrid perovskites had previously been considered as the potential cause of…
