Spherical Solar Cell
Conventional flat solar cells are unable to effectively harness indirect sun light. The sun takes on a many different positions according to the season and time of day, so in order to obtain a stable supply of power, there is a need to change the orientation of the solar cell by constantly following the sun. Sphelar® solar cells developed by Kyosemi Corporation, Japan, captures light from all directions, including reflected light and diffused light. In addition, there is no need for the superfluous operation of tracking the sun. The spherical light-receiving surfaces achieve unprecedented high generation efficiency. With a diameter of a mere 1 to 1.5mm, Sphelar can be connected either in parallel or in series. This enables diverse spherical products to be created, such as dome-shaped solar cells and "flexible" solar cells aligned on soft film substrates. Sphelar is perfect for situations where the installation of a flat solar cell would block the field of view. It is also possible to create "power-generating window glass" while maintaining a certain level of transparency. Conventional flat solar cells are produced by slicing crystalline silicon ingots, generating a large quantity of "Kerf loss" in the production process. In contrast, 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. This results of course in a dramatic reduction in costs, and helps ensure the efficient use of silicon, a finite resource. Sphelar is an environmentally-friendly product, not only in terms of performance but also during the production phase. There are numerous possibilities for a variety of new applications which capitalize on the properties of Sphelar in a variety of different fields and situations.
