Perovskite solar cells have been gaining attention lately as their energy efficiency starts reaching that of silicon cells and with good reason! These cells are simple and cheap to produce and have a high level of flexibility that would lend themselves to a variety of applications. The problem, however, has been getting them to last for more than a couple of months.

Now, researchers from Georgia Institute of Technology, University of California San Diego and Massachusetts Institute of Technology may have found a key to fix this challenge. “Perovskite solar cells offer a lot of potential advantages because they are extremely lightweight and can be made with flexible plastic substrates,” said Juan-Pablo Correa-Baena, an assistant professor in the Georgia Tech School of Materials Science and Engineering. “To be able to compete in the marketplace with silicon-based solar cells, however, they need to be more efficient.”
