Spherical solar cells

Spherical shape of a solar cell sounds unique and unparalleled in its capability to achieve a better conversion rate between solar energy and electricity than the conventional flat cell. In fact, the sphere, because of its own shape, must be ideal to absorb direct and reflected lights while a flat one can't take the reflected light from the reverse side. The production process, Kyosemi Corporation, the manufacturer of the solar cell, seems to be also incomparable to dramatically reduce wasted material of silicon. The spherical solar cell, Sphelar®, is just one millimetre in diameter, seem to have great potential for varieties of application.

One of the new applications, Kyosemi supplies, is SphelarVoice ™, a battery-free wireless audio optical information system using Sphelar® cells.

I've found a good video movie on YouTube that resents the uniqueness of these points. It's should be better than a lengthy description in writing. Seeing is believing. Take a look at the video!
