Sphelar® is the trademark given to a proprietary spherical solar cell product Kyosemi Corporation has developed on its own. Unlike conventional flat solar cells, Sphelar® takes on a spherical shape, which makes it capable of power generation with greater efficiency and flexible applications. This tiny solar cell measuring a mere 1 mm across holds huge potential, standing ready to contribute to the realization of everything from ubiquitous network society to clean-energy society. The Solar Cells can be used in any handheld or other wireless application you can imagine.

 

Each cell can give an output of 0,6 V or 2,5 mA and can be combined in different versions of parallel and seriel. See below.
