Just found this article titled
"Purple Pokeberries Hold Secret to Affordable Solar Power Worldwide" from Science Daily that seems very in line with permaculture principles. Apparently the red dye from the pokeberry coats the fibers of the solar cell acting as a photon trap and absorber. This is especially helpful because the solar cells will efficiently collect light from a wide angle range, from sun up to sun down without having to reorient the panels.
This is my first post on this forum, I look forward to sharing permaculture ideas with all of you.
