Researchers generate clean energy using bacteria-powered solar panel

Researchers have taken the next step in the evolution of bacteria-powered energy

13-Apr-2016

For the first time ever, researchers connected nine biological-solar (bio-solar) cells into a bio-solar panel. Then they continuously produced electricity from the panel and generated the most wattage of any existing small-scale bio-solar cells - 5.59 microwatts. "Once a functional bio-solar ...

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

27-Nov-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 ...
