Tuning out the defects for more powerful perovskite solar cells
Scientists in the UK and Japan used the latest imaging techniques to observe the inner workings of a perovskite solar cell at the scale of a few nanometers. Their findings suggest that a single defect is responsible for both limiting initial performance and causing degradation of the cell. By altering chemical compositions and process parameters, the appearance of this defect can be quickly reduced, and the group is confident that its finding could quickly be applied in large-scale processing as well.
