A team of scientists based at Cambridge, Oxford, Bath, the Massachusetts Institute of Technology and Delft has developed a way to fix defects in perovskite solar cells and make them more efficient. The team found that cells that were exposed to light for 30 minutes at one percent to 89 percent humidity levels had fewer defects and were more efficient at converting sunlight into electricity. In addition, when water was applied to the cells afterwards, the surface was converted into a protective shell, preventing further defects and increasing the longevity of the performance improvement.
A team of scientists based at Cambridge, Oxford, Bath, the Massachusetts Institute of Technology and Delft has developed a way to fix defects in perovskite solar cells and make them more efficient. The team found that cells that were exposed to light for 30 minutes at 40-50% humidity levels had fewer defects and were more efficient at converting sunlight into electricity. In addition, when water was applied to the cells afterwards, the surface was converted into a protective shell, preventing further defects and increasing the longevity of the performance improvement.
