Paint-on Solar Cells

No, I'm not talking about a new type of Photo-voltaic cell, nor am I talking about old horses, I'm talking about yet another additive that you can mix with regular house paint that converts light into electrical energy.

Now it has a few specific requirements, such as being applied to a conductive surface, so you can't just go out to Home Depot and toss a fresh coat of paint with this additive onto your stucco.  It also only has an efficiency of about 1%, significantly less than the 10-15% you get from your typical silicon PV arrays.  But, this additive is significantly cheaper than PV, so you may just get a return on investment depending on what type of structure you apply the paint to; it just won't be applied during your next home remodel.

This brings up a point I made April 2011 in my post about The Next Asbestos.  When the formulation for this nano-additive becomes more efficient and usable on any substrate, imagine applying it along with the heat-resistant additive mentioned in my blog post.

Read the press release from the makers of the additive at Notre Dame's Center for Nano Science and Technology.
