By Morgan McCorkle – “One of the dreams is to bring home some polymer paint from the hardware store, spray it on a window and make your own solar cell because it self-orders into a structure that can generate electricity,” ORNL’s David Geohegan said.
“But right now there are many unknown things that happen when you spray it down and it dries. Changing the electrical property of a polymer also changes its structure when it dries, so understanding this process is one of our big science mysteries.”
Modeling the system through quantum calculations helped the researchers determine that heavy hydrogen changes the molecules’ vibrations, which indirectly but significantly affects the material’s electronic properties. more> http://tinyurl.com/pwbx76b
