Light hitting the plate is diffused to the edges where silicon PV cells wait to generate electricity

The GreenSun Energy solar cell uses a fraction of the silicon found in existing cells and can even generate power when not in direct sunlight
Professor Renata Reisfeld has spent the last 20 years researching solar energy production
One of the most common ways to turn the sun's energy into electricity is by persuading silicon to give up some of its electrons. But it's also quite expensive, so any innovation that helps reduce the cost of solar cell production is welcome. Researchers in Israel have come up with a cell that uses only 20% of the silicon in a standard cell yet yields similar amounts of electricity. It does this by diffusing any light that falls on its surface and sends it off to photovoltaic collector strips on each of its sides. And it doesn't even need bright sunlight to operate.
