These Ultra-thin Solar Cells can Turn any Surface into a Power Source

These solar cells are thinner than human hair and supply 18 times more power per kilo than standard cells while weighing 100 times less. Their inventors at MIT say the panels are printable using ink-based materials and are quick, easy, and cheap to make. They can stick to any surface, from the wings of a drone to the sails of a boat.
