Over the years I’ve seen concepts of solar-powered sunglasses advance and depart, but the dream of for some reason wearing solar panels on my face has remained elusive — until nowadays. Genius engineers at Karlsruhe Institute of Technology fill successfully made a pair of shades with biological solar cell lenses — and you don’t even fill to stare directly at the sun for them to work.
The lenses fill been reduce like ordinary glass or plastic to fit in a commercial frame, and are similarly light and obvious. biological solar cells aren’t particularly efficient, but they are flexible and versatile, able to be assign in situations where a rigid, opaque cell isn’t an option.
“The Solar Glasses we developed are an example of how biological solar cells may be employed in applications that would not be feasible with conventional photovoltaics,” said Dominik Landerer, a PhD student at KIT who worked on the project, in a news release from the school.
Each arm of the sunglasses houses a custom PCB that converts the current and uses it to race, in this case, two small displays that note temperature and brightness. Not certain why you’d need a display to inform you how quick-witted it is out there, but hey, it’s a research project.
After supplying the displays, the cells generate approximately 200 milliwatts of excess power. That’s not going to finish much for your phone, but it will race or trickle charge a low-power device like a step counter, wireless transmitter or small speaker. They work in dimmer light, too, like that of a domestic or office. In this case there isn’t even a battery in the assembly — it’s utter accomplished with the energy collected in real time.
The researchers envision more piquant applications as the technology and manufacturing methods mature. They’ve published their methods in the journal Energy Technology.
