Why it is important: The large scale adoption of “green” energy generaion is mostly a function of its cost and the abundance of its raw materials. Discovered 1839 by Gustav Rose in the Ural mountains and named after mineralogist Lev Perovski, Perovskites based on a metal and a halogen are known candidates for inexpensive solar cells- with an efficiencey on par with silicon based cells- plus they can even be dissolved in liquid and 3d printed on film. However, there is a major obstacle to making solar cells of perovskites as the base material: their efficiency degrades quickly when constantly exposed to oxygen and light- a pretty basic problems for a solar cell.
Now, John Labram of the OSU College of Engineering has published new papers about how to make them last much longer… This may lead to very inexpensive solar cells with huge manufacturing advantages and erfficiencies exceeding 30%
