While Elon was busy stuffing Twitter around, a new paper-thin photovoltaic was developed. "These thin-film solar cells are one-hundredth as heavy as conventional solar cells while generating 18 times as much power per kilogram." u/IEEEorg https://spectrum.ieee.org/thin-film-solar-panels ☀️

"MIT researchers have developed what they say is a scalable fabrication technique to produce ultrathin, lightweight solar cells that can be adhered to any surface."

>"The fabric modules had a power density of 370 watts per kilogram and weighed 0.1 kilogram per square meter. Commercial residential silicon solar panels, by contrast, have a power density of 20 W/kg and weigh 10.7 kg/m2"
