NSF is the national science foundation. Massive government tech work and dispersal of grants. The article cited here talks about using CIGS nanocrystals in a solvent to make spray on solar cells! (CIGS= COPPER INDIUM GALLIUM SELENIUM) this means ultra cheap and versatile solar cells! they can be sprayed on metal panels made into clothes or put on cars!! Much cheaper and easier. They have lower efficency than silicon panels but who cares if you can get a spray can for 5 bucks to make a solar panel! very good article. check it out!
