Materials: Spherical micro solar cells

What you are seeing here is the Sphelar solar cells. They are made by the Kyosemi Corporation, which debuted at the PV Expo 2010 in Tokyo.

The purpose of the Sphelar solar cells is to improve on regular solar panels. You know how most solar cells are flat, and are at only one angle? That isn’t really an accurate way to collect the sun, but Sphelar solar cells are solidified drops of silicon that can be molded into any shape. For example, they can be placed on a curved dome that allows the sun to hit it from any angle.
