"Imagine a world where electrical circuits in many of our current day technologies such as computers, navigation aids and even mobile phones can simply generate their own electricity just by exposing them to� sunlight. Definitely one step ahead of traditional solar cell PV systems as we know it - there would be no need for separate components to power these devices and maybe no need for a battery to store energy. This is science fiction that could soon be science fact thanks to a research team at the University of Pennsylvania."
