A team of scientists based at Cambridge , Oxford , uk , 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 cell was converted into a protective shell , preventing further degradation and increasing the likelihood of the performance improvement .
