Graphene is still interesting. I am planning to build prototype so you could make some kind of nano-coal-coating into paper or anything from burning wood and using ultrasound.
So maybe make your own solar panels, this way. Not so effective as the industrial, but they would be cheap. Ultra sound nozzles do cost kinda lot..
