Just a few days after Elon Musk’s SolarCity announced an improvement that would make solar panels the most efficient in the world, Panasonic announced a product that is about half a percent more efficient.
“What's cool about Panasonic's record-breaking prototype is that it was mass-produced, and able to convert 22.5 percent of sunlight into electrical energy straight off the production line, which means it'll be easily commercialised and presumably relatively cheap for consumers,” Science Alert reports.
