Sunglasses generate solar electricity

Eye glasses generate solar electricity, researchers at the Karlsruhe Institute of Technology develop semitransparent organic solar cells inside glasses for power microprocessors or future solar-powered mobile applications. Futuristic technology of flexible, transparent and light organic solar cells is suitable for applications that can not be realized with conventional silicon solar cells.

Researchers at the Karlsruhe Institute of Technology developed sunglasses equipped with colored and semitransparent solar cells attached to the lens for the microprocessor and two electric displays. The research team paved the way for other future applications such as the integration of organic solar cells for window or overhead glazing.

"We bring solar power to places where other solar technologies fail," said Dr. Alexander Colsmann, Head of Organic Photovoltaics Group at KIT’s Light Technology Institute (LTI).

Smart sunglasses have solar cell lenses and are fitted perfectly on a commercial frame, about 1.6 millimeters in thickness and weigh about 6 grams or the same as traditional sunglasses lenses, while microprocessors and two small displays are integrated into the solar glass temple.

Solar glasses also work in indoor environments under illumination up to 500 Lux which is the usual lighting in the office or home where each "smart" lens still produces 200 microwatt of electric power or to operate devices such as hearing aids or step counter. The researchers report the findings to Energy Technology. Sunglasses generate solar electricity

"Our Solar Glass is an example of how organic solar cells are used in applications that do not fit conventional photovoltaics," said PhD student Dominik Landerer.

This solar cell is based on hydrocarbons and has the mechanical flexibility and opportunity to adjust color, transparency, shape, and size according to the desired application. Colsmann said organic solar modules also have prospects for applications on building glass facades.
