Stanford technology makes metal wires on solar cells nearly invisible to light

Stanford technology makes metal wires on solar cells nearly invisible to light Stanford CA (SPX) Nov 30, 2015 - A solar cell is basically a semiconductor, which converts sunlight into electricity, sandwiched between metal contacts that carry the electrical current. But this widely used design has a flaw: The shiny metal on top of the cell actually reflects sunlight away from the semiconductor where electricity is produced, reducing the cell's efficiency. Now, Stanford University scientists have disc ... more
