In a study to be published on Friday, May 7 in the journal <i>Science<\/i>, the team demonstrates a \u201cmolecular glue\u201d that keeps a key interface inside cells from degrading. The treatment dramatically increases cells\u2019 stability and reliability over time, while also improving the efficiency with which they convert sunlight into electricity.<\/p>\n<p>\u201cThere have been great strides in increasing the power-conversion efficiency of <a href=\"https:\/\/phys.org\/tags\/perovskite\/\" rel=\"tag\" class=\"\">perovskite<\/a> solar <a href=\"https:\/\/phys.org\/tags\/cells\/\" rel=\"tag\" class=\"\">cells<\/a>,\u201d said Nitin Padture, a professor of engineering at Brown University and senior author of the new research. \u201cBut the final hurdle to be cleared before the technology can be widely available is reliability\u2014making cells that maintain their performance over time. That\u2019s one of the things my research group has been working on, and we\u2019re happy to report some important progress.\u201d<\/p>\n<p>Perovskites are a class of materials with a particular crystalline atomic structure. 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. The efficiency of those cells has increased quickly and now rivals that of traditional silicon cells. The difference is that perovskite light absorbers can be made at near <a href=\"https:\/\/phys.org\/tags\/room+temperature\/\" rel=\"tag\" class=\"\">room temperature<\/a>, whereas silicon needs to be grown from a melt at a temperature approaching 2700 degrees Fahrenheit. Perovskite films are also about 400 times thinner than silicon wafers. The relative ease of the manufacturing processes and the use of less material means perovskite cells can be potentially made at a fraction of the cost of silicon cells.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>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.
