Spray-on Solar?

I was reading articles on a site called Celsias (http://www.celsias.com/article/five-awesome-solar-trends-how-they-will-change-wor/) and came across a really interesting post about some new solar energy things we'll be seeing. One that I found especially intriguing is the idea of spray-on solar. Apparently, the geniuses at M.I.T. have found a way to print solar cells on paper (similar to printing ink on paper, except instead of ink, an organic semiconductor material is put on the paper).It looks like this:

 The paper can still be folded and is virtually indestructible, according to the article. The article also said that the researchers are working to improve this method so that eventually the solar cells could be sprayed on a variety of surfaces. How cool would that be??
