A team of researchers at French WYSIPS (what you seem is photovoltaic surface) claim to have developed a film that’s accurate to within a pixel. The technology they say can provide a high-definition solution applicable to all types of screens. Just like touch screen technology, Wysips is designed to become an integral part of the screen, allowing all tomorrow’s telephones to produce their own power from the sun.

WYSIPS responds to the global need for connectivity, mobility and autonomy. They say: “Thanks to WYSIPS, no more chargers and wall sockets: your phone charges automatically on a café terrace, walking down the road, or wherever and whenever you take it. A WYSIPS phone produces, stores and uses its own energy: you’ll never experience a flat battery again!”
