Double the Efficiency, Double the Fun? Two Sided Solar Cells?

October 29, 2008 at 10:15 pm 1 comment

I ran across an interesting concept today, 2 sided solar cells.  A Swiss scientist, Michael Grätzel of the Swiss Federal Institute of Technology in Lausanne, Switzerland (http://isic2.epfl.ch/page58671-en.html) has come up with a concept where a solar cell can be doubly efficient as it can collect light for both sides.

The article can be found on New Scientist.com (http://technology.newscientist.com/article/dn15059-twofaced-approach-creates-solar-cells-to-dye-for.html?DCMP=ILC-hmts&nsref=news3_head_dn15059)

Excerpt: “Solar cells could become cheaper and more efficient, thanks to a cheap dye-based design that can capture sunlight from both sides simultaneously.

Dye-sensitized solar cells contain no silicon, but instead rely on the interaction between light and a dye coated on to tiny grains of titanium dioxide, a cheap white pigment.

The grains sit in a liquid that acts as an electrolyte, picking up electrons released by the dye as it absorbs light, generating current.

This is a very interesting concept in that it takes a different approach to generating solar power than the silicon panel.  I hope that they can continue to develop this and bring it to market soon!

    yes, getting it to market is the thing. how many of these new technologies never even make it to market? i’m always on the look out for a investment but it’s hard predicting which one will come off.
