HONG KONG Researchers in Hong Kong have taken a new type of solar cell developed in Japan to the next level of efficiency, opening the door to a wide range of applications.
Perovskite solar cells, as they are called, use a thin film of perovskite crystal that combines metal atoms, such as lead, and organic substances containing elements such as bromine, to generate current. These cells can be produced cheaply and easily using printing technology to apply the material to a substrate or other object.
