Spherical microsolar cell applications
Two new photovoltaic device prototypes: a flexible see-through Sphelar® sheet; and, a dome-style Sphelar® module. Sphelar® is the trademark given to a proprietary spherical solar cell product Kyosemi Corporation has developed on its own. This tiny solar cell measuring a mere 1 mm across. Sphelar® captures light from all directions, which means it can catch reflected light and diffused light. In addition, there is no need for the superfluous operation of tracking the sun. Sphelar is produced using a unique process whereby melted silicon is subjected to free fall , and spheres are formed naturally by the microgravity conditions, so there is hardly any waste of raw materials at all. Pretty much like a modern version of the shot tower, but for use in the war on climate change (WACC).
