Solar glasses generate solar power

Researchers from KIT present sunglasses with colored, semitransparent solar cells applied onto lenses that supply a microprocessor and two displays with electric power.

The "smart" Solar Glasses designed as a case study by the scientist and his team at KIT, is self-powered to measure and display the solar illumination intensity and ambient temperature. The solar cell lenses, perfectly fitted to a commercial frame, have a thickness of approx. 1.6 millimeters and weigh about six grams – just like the lenses of traditional sunglasses.

The microprocessor and the two small displays are integrated into the temples of the Solar Glasses. They show the illumination intensity and the ambient temperature as bar graphs. The Solar Glasses also work in indoor environments under illumination down to 500 Lux, which is the usual illumination of an office or a living area.

"The Solar Glasses we developed are an example of how organic solar cells may be employed in applications that would not be feasible with conventional photovoltaics," stresses PhD student Dominik Landerer who largely contributed to the development of the solar glasses at the Material Research Center for Energy Systems of KIT.

In the eyes of the engineer, these solar cells, which are based on hydrocarbons, are very exciting devices due to their mechanical flexibility and the opportunity to adapt their color, transparency, shape, and size to the desired application.
