Oxford PV has developed a new commercial-sized solar cell that converts 28.6% of the sun’s energy into electricity, a new world record for production-ready technology that was certified by Germany’s Fraunhofer ISE research institute.
The cell was made by depositing a thin film of perovskite onto a conventional silicon solar cell, giving the tandem-solar cell a much higher efficiency than that of conventional silicon-only solar cells that average 22-24% conversion efficiency.
