Solar spray Scientists at Sheffield have made another leap forward in the realms of renewable energy with the development of spray-on, highly efficient solar cells.The researchers have discovered a way to spray perovskite, a promising new solar technology that combines high efficiency with low production costs.Spray painting this material is a new development that means very little is wasted, and can be scaled up to high volume manufacturing, like spraying paint onto a car.There is a lot of excitement around perovskite based photovoltaics," said lead researcher Professor David Lidzey.Perovskite cells now have efficiencies of up to 19 per cent
