Researchers at the US Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL) have found that a tin-lead perovskite cell can overcome problems with stability and improve efficiency, with their latest experiment yielding a 25.5% conversion efficiency.
Perovskite solar cells have become the focal point of many university-led studies in the past year. In the first of a new series of article on PV Tech profiling some of the leading cutting-edge solar technologies, Edith Hancock explores what is being done to remove bottlenecks to the growth of perovskites.
