Danish researchers have developed paper-thin OPV (organic photo voltaic) solar cells. Sheet of these cells could be applied to areas such sides of buildings, window curtains, car roofs, just to name a few. And now Germany — a country that gets half of its energy from solar panels — has invested $21 million dollars to help advance the research.
