Researchers develop coating for improved wettability and enhanced carrier lifetimes in perovskite solar cells
Researchers from the University of Surrey, the University of Warwick and the University of New South Wales have reported a nanoscale “ink” coating of aluminum oxide on metal halide perovskite, that stabilizes the drop in energy output that presently plagues perovskite technology.
"In the past, metal oxides have been shown to either benefit or degrade the performance of perovskite solar cells. We’ve identified aluminum oxide which can improve performance and minimize the drop in efficiency during conditioning of perovskite solar cells", said Hashini Perera, Study Lead Author, University of Surrey.
