Researchers Develop Transparent Solar Concentrator That Could Cover Windows, Electronics

Scientists at the University of Michigan announced this week the creation of a "transparent luminescent solar concentrator" that could turn windows and even cellphone screens into solar-power generators. This technology could mean that one day entire skyscrapers might be able to generate solar power without blocking out light or ruining tenants' views. The material works by absorbing light in the invisible spectrum (ultraviolet and near infrared) and then re-emitting it in the infrared. The infr...
