Solar cells may help the development of green energy technology

Researchers are searching for better materials to harness solar energy, but an explanation for the efficiency of one promising substance, perovskites, has proven elusive.

However, thanks to new research from Cambridge University, scientists are no longer in the dark about perovskite’s benefits.

It turns out that the material’s variegated chemical structure protects it from the electronic pitfalls associated with similar materials and could pave the way to bettering it and other green-tech materials in the future.

Perovskite, a high-performance solar cell material that converts more of the sun’s rays into electricity, has proven its worth in lab tests after one another.

However, after a decade of laboratory breakthroughs, it was unclear why the material performed so effectively until now.

Using a variety of microscopes, Cambridge University researchers were able to identify perovskite’s secrets by surveying its chemical, structural, and electrical disorder by using a few different microscopes.

The groundbreaking findings could hasten perovskite’s development, allowing scientists to further tweak its material’s composition and integrate it into commercial solar arrays, and even help light the way for energy research using other materials.
