LEDs made from 'wonder material' perovskite

Colourful LEDs made from a material known as perovskite could lead to LED displays which are both cheaper and easier to manufacture in future. A hybrid form of perovskite -- the same type of material which has recently been found to make highly efficient solar cells that could one day replace silicon -- has been used to make low-cost, easily manufactured LEDs, potentially opening up a wide range of commercial applications in future, such as flexible color displays.
