A Korean firm, Kyosemi Corporation, has developed a highly
efficient spherical solar cell. It's called the Sphelar and
represents a huge leap forward in solar development. Instead of
conventional solar cells which lay flat and only have 1 surface
to collect the sun's energy, these spheres, measuring between
1-1.5mm in diameter, will be able to harness the energy from
most of their whole surface. This also gives their panels
flexibility as their structures do not need to be rigid,
allowing them to be used in more applications than conventional
PV. As an added bonus these cells do not block light and can
therefore be embedded in clear objects without fully
compromising clarity, giving energy producing windows a chance.
Physorg reports that "the Sphelar is made by a process of melted
silicon that is subjected to free fall, whereby spheres are
created naturally by the microgravity conditions. The result
creates little or no waste of raw materials. This feature is
cost effective and provides efficient use of the r
