Colorant from common berries enhances photovoltaic solar cells

Pokeberries (the fruit of Pokeweed/Phytolacca spp.) “… grow on every continent but Antartica,” observes David Carroll, Ph.D., director of Center for Nanotechnology and Molecular Materials at Wake Forest University, Illinois. He and fellow nanotech scientists have discovered that red dye made from Pokeberries can be used to coat inexpensive fiber-based solar cells to enhance the absorption of sunlight for conversion into electrical power.
