Pokeberries Prove to Be Valuable in Solar Panel Production

Scientists at Wake Forest University have discovered that pokeberry dye can improve the efficiency of some solar cells. When applied to fiber-based solar cells, the berry's dye acts as an absorber, helping the cell's fibers capture more sunlight to convert into power. Fiber-based solar cells can produce twice as much power as current flat-cell technology and are less expensive to produce.
