Not only are these decorative solar panels pretty, they also work indoors. Based in Finland, the VTT Technical Research Centre can print a maximum of 100 meters of organic solar paneling in just one minute.
This innovation in solar energy generates power from the sun's rays well as light sources inside. The mass production printing process uses 0.2mm thick flexible photovoltaic paneling that's able to have patterns printed on it. Capable of being functional and a design element, the decorative solar panels can be used to power small sensors and electronic devices.
In addition to being placed on walls and windows, the panels can be stuck to everything from billboards and print ads to equipment and machinery.
