From a technology review article-
here.

Harvesting ligh in from northern exposure windows and low light conditions.

Phil-what do you think?

I think this would be absolutely amazing if they have it perfected. That would be a great advance in green technology. I've thought about something like that coming up in the future, I just haven't heard about it up until now.

The big thing is long term reliability.  If it can be repaired or resprayed on site that would go a long way to easing investors fears.

Here are a couple of other sites that describe printed solar cells as well.

Nanosolar has been around for a while.  From what they published, crystaline efficiencies are 14% while printed efficiencies are 11%.  I'd imagine sprayed on would be about the same, meaning you'd need 25% more area for equal power.

Crystaline panels are the standard with 25 year warrantees, I have no idea what the other warrantees are.  Looks great though.  I think film panels are half the price or less of crystaline so even if they only lasted a decade they'd still be viable.  If long term reliability can be codified they may replace standard panels.  I think solar has a bright future!  (Sorry, couldn't resist )

If they could sing, it would be-
"My future's so bright, I gotta wear shades."

That was great since it could mean more and more can avail  or afford having a solar energy source set up using the solar films. And if they could make it lasts just like solar panels, no doubt that the future will be shining brightly.

It's a long term reliable technique, it can be an advanced green technology. Solar is a great resource to generate energy, so this is a good technology.

The top three expenses for solar are the panels, the inverter, and the mounting rail system in that order.  Films require no mounting and are cheaper than panels so they attack two of the three top costs.  Hopefully inverter prices will come down as production increases.
