A discovery by scientists at University of Groningen, Netherlands has shown that tin-based perovskite solar energy materials could more than double solar PV efficiency.

The paper, published in the journal Nature, reports that extra ‘hot’ electrons generated by sunlight but normally wasted last longer than expected on tin. The team have calculated that if this heat can then be harvested maximum efficiency could be as high as 66%, more than twice the typical 27% of today’s solar cells.
