Blueberries may be key to cheaper solar power

Professor Aldo Di Carlo in the Department of Electronic Engineering at the University of Rome Tor Vergata in Italy is a big fan of blueberries. He likes them, but not only to eat.

When Di Carlo sees a blueberry, what he really sees is a potential energy source. He is leading a research team that is exploring the use of several dyes, including pigments derived from blueberries, to improve solar panel production. The research is focused on the role of organic semiconductors in what are known as dye-sensitized solar cells, or DSSCs.
