Blueberries Used To Capture Solar Power

We just reported on the breakthrough in solar dyes in New Zealand. Now, researchers in Italy have discovered that blueberries have natural pigments that absorb sunlight extremely well. Apparently, dark-colored berries outperform most other plant species when it comes to spectral absorption of sunlight. The blueberry pigment, called, anthocyanine, can be used to make dye-sensitized solar cells, which require no silicon to make.

Extraction of the pigment is accomplished through a fairly simple and quick procedure involving chemical purification, according to Professor Di Carlo in the Department of Electronic Engineering at the University of Rome Tor Vergata.
