Video: Sunglasses produce electricity from sunlight

German researchers have successfully built sunglasses that can generate electricity using hidden optical cells in the glasses.

The energy obtained from the glasses is used to run electrical equipment.

Sunglasses contain many flexible organic photovoltaic cells in many shapes and colors. The glass frame is also equipped with electrical equipment including: microprocessor, two sensors and two displays.

The energy obtained from the glasses is used to run electrical equipment, measure the lighting and electrical equipment around, parameters are indicated by a column chart.
