New solar cell turns raindrops into electricity

Researchers from two Chinese universities have developed a solar cell that can produce electricity from light and water, enabling a solar panel that works in the sun or rain.
The scientists from Ocean University of China in Qingdao and Yunnan Normal University in Kunming developed a highly efficient and flexible dye-sensitized solar cell and then coated that cell with a one atom-thick layer of electron-enriched graphene.
The new all-weather solar cells can be excited by light on sunny days and
