Scientists from the University of
Pennsylvania have developed a photovoltaic circuit that is entirely
self-powered as long as it’s left in a beam of light. The researchers
claim this new circuit could eventually result in a new line of
consumer devices or even model the human brain.
"This as the potential to create a new generation of
optical and electronic devices," said Dawn Bonnell, a scientist from
the University of Pennsylvania who co-authored a recent ACS Nano paper
describing the research. "The touchscreen of your computer could act as
both the electrical charger and the computer chip."
Right now Bonnell and her colleagues can only coax minuscule
amounts of electricity from their photovoltaic circuits, far too little
to power consumer electrical devices. Those amounts could quickly
