Researchers at Wake Forest University (USA) center for Nanotechnology and Molecular Materials have discovered that by coating fiber-based solar cells with the red dye made from Pokeberries (a common weed) it can help the cell's tiny fibers trap more sunlight to convert into power.
Plastic fiber cells can produce as much as twice the power that current flat-cell technology can produce, Since the fibers create much more surface area, the fiber solar cells can collect light at any angle - from the time the sun rises until it sets. The dye (made from pokeberries) can be sprayed on to the cells prior to installation.
The hope is that this type of low-cost solar cell can be made to work with local, low-cost agricultural crops like pokeberries and a means of production that emerging economies can afford.
