Transparent Solar Panels

Imagine if instead of looking out your window to see your solar-panel array, your windows were your solar panel array. Sphelar solar cells can be built into windows, whether they're flat or curved. Instead of chasing the sun, they'll capture the sun from all angles, then convert it to energy.

Sphelar cells are solidified silicon drops measuring 1.8 mm in diameter and are highly transparent, which is advantageous for a number of reasons. They can be embedded in glass to create a transparent solar cell window, capable of absorbing light from any direction or angle. Because both sides of the glass can collect light, this should translate into highly efficient energy harvesting.
