Pokeberry Power

I am slightly skeptical of this, but it would be nice if it works out:

Carroll says a red dye made from pokeberries can be used to coat a new type of solar cell that's produced from millions of tiny plastic fibers. Unlike traditional solar units, fiber cells — thanks to a patented design that exposes more surface area to the sun's rays — can produce a usable amount of power even at sunrise and sunset.

The dye acts as an absorber helping the cell's tiny fibers trap significantly more sunlight during the day, compared to current solar systems, that then gets converted into energy. The technology is especially promising because it is able to generate twice the total kilowatt-hours per day than traditional silicon-based units.
