Solar Cells That Glow


A new type of solar cell has been developed which absorbs light during the day and shinesby the night. The cell is made of perovskite, a futuristic material, that can produce cheap solar power as it has a high conversion rate. The technology has widespread use. It can be used to make window panes which will absorb sunlight during the day and act as display screens at night.
