![]() ![]() The difference is that perovskite light absorbers can be made at near room temperature, whereas silicon needs to be grown from a melt at a temperature approaching 2,700 degrees Fahrenheit. The efficiency of those cells has increased quickly and now rivals that of traditional silicon cells. A little over a decade ago, researchers showed that perovskites are very good at absorbing light, which set off a flood of new research into perovskite solar cells. Perovskites are a class of materials with a particular crystalline atomic structure. That’s one of the things my research group has been working on, and we’re happy to report some important progress.” “But the final hurdle to be cleared before the technology can be widely available is reliability - making cells that maintain their performance over time. “There have been great strides in increasing the power-conversion efficiency of perovskite solar cells,” said Nitin Padture, a professor of engineering at Brown University and senior author of the new research. The treatment dramatically increases cells’ stability and reliability over time, while also improving the efficiency with which they convert sunlight into electricity. In a study published in the journal Science, the team demonstrates a “molecular glue” that keeps a key interface inside cells from degrading. ![]() A research team from Brown University has made a major step toward improving the long-term reliability of perovskite solar cells, an emerging clean energy technology. ![]() Researchers have used self-assembled monolayer "molecular glue" totoughen interfaces in perovskite solar cells to make them more efficient,stable and reliable. ![]()
