Solar Cell: 100% Plastic

Take a 1 to 10 mm thin layer of polymer and spread it on a conductor plane, creating a sturdy surface dipole to achieve an efficient low work function and air-stable conductor – that’s exactly what researchers at Georgia Tech did. The exploited polymers were both environmentally friendly and cheap, as well as compatible with present-day production techniques, implied Georgia Tech COPE’s Bernard Kippelen. What it means, is that this technology can change the development of printed electronics (used in gadgets and solar panels), reducing its cost and thus making it far more affordable.
