Japanese company Kyosemi has developed a revolutionary spherical micro solar cell that is capable of capturing sunlight from all directions. Called the Sphelar, the cell shuns the traditional flat substrate photovoltaic design and opts for much more efficient shape – the sphere. While traditional flat solar cells are easy to design and produce, their main problem is that their efficiency relies on their relative position to the sun. While some companies have addressed this with motorized frames that follow the sun’s path, Kyosemi has gone for a completely new approach that doesn’t need costly motors to work.
