Researchers have clarified the relationship between air exposure and enhanced electric proprieties in perovskite solar cells. Perovskite solar cells are the rising star in the photovoltaic landscape. Since their invention, <10 years ago, their efficiency has doubled twice and it is now over 22% – an astonishing result in the renewable energy sector. Taking the name ‘perovskite’ from the light-harvesting layer that characterizes them, these solar cells are lighter, cheaper, and more flexible than the traditional crystalline silicon-based cells.
Perovskite solar cells are usually exposed to ambient...
