Spray painting perovskite-based photovoltaics
A team of scientists at the University of Sheffield, writes David Manners, are the first to fabricate perovskite solar cells using a spray-painting process. It is a discovery that could help cut the cost of solar electricity.
Experts from the university’s Department of Physics and Astronomy and Department of Chemical and Biological Engineering have previously used the spray-painting method to produce solar cells using organic semiconductors – but using perovskite is a major step forward.
Efficient organometal halide perovskite-based photovoltaics were first demonstrated in 2012. They are now a very promising new material for solar cells as they combine high efficiency with low materials costs.
The spray-painting process wastes very little of the perovskite material and can be scaled to high volume manufacturing – similar to applying paint to cars and graphic printing.
The lead researcher is professor David Lidzey.
