Solar Startup Born in a Garage Is Beating China to Cheaper Panels

Australia-based SunDrive has made a materials breakthrough that promises to increase the efficiency and lower the cost of solar panels.

About seven years ago, Vince Allen barged into the garage he shared with some flatmates in a Sydney suburb and set about trying to shake up the solar industry. He was at the time a PhD candidate at the University of New South Wales, and he had an idea for making solar panels much cheaper: replace the expensive silver typically used to pull electricity out of the devices with plentiful, cheap copper.

Labs and well-funded giants had already struggled with this same attempt to ditch silver. Allen remained undeterred and built his own equipment to test one idea after another at a quick clip, until he found a technique that worked. SunDrive Solar, the company he co-founded in 2015 based on this research, proved this week that it has produced one of the most efficient solar cells of all time, according to a leading independent testing laboratory. And SunDrive did so with copper as the metal at the core.
