What you see here are Sphelar solar cells. They are manufactured by the company Kyosemi, which debuted at the 2010 Expo in Tokyo PV.

The purpose of the Sphelar solar cells is to continually improve for solar cells. You know, like most solar cells are flat and are in a corner? This is not really an accurate way to collect the sun, but solar cells are Sphelar solidified drops of silicon that can be molded into any shape. For example, they can be placed on a curved dome of the sun taken from every angle.

As you can see, the material Sphelar is almost transparent. This allows the user to set a standard window, and he is a solar generator. It is also slightly tinted, which will keep the blinding light when it must be kept away.

I assume that the potential of this technology is pretty endless. For example, you can imagine, all the windows of skyscrapers of more solar energy producers? And if every house had these cells Sphelar of your windows? Granted, I do not know how much energy you can get from these objects, but hey, every bit counts when saving energy.
