These Flexible Solar Cells Don't Need Any Motors to Rotate with the Sun

These flexible solar cells are based on kirigami -- an ancient Japanese style of folding and cutting art much like origami. These kirigami solar cells allow the panels to turn to follow the sun, capturing 40% more energy than when stationary and without any heavy or expensive motors needed.

The twisted, accordion style of the folds means that when the entire panel is stretched, the long thin cells un-flatten and rotate to the side. With this natural rotating method, the eco-friendly technology becomes eliminates the need for energy that is wasted on motors.

These lightweight, flexible solar cells are also much thinner than usual, making them even less expensive -- perfect for home installations. With the ever increasing desire to turn to solar energy, these economic panels will hopefully make that a more accessible reality for homeowners.
