Good find! Low-Cost 3-D Solar Cells Undergo Space Testing
?"Three-dimensional solar cells made with very low-cost materials are being tested in the proving grounds of space. These novel photovoltaic devices, developed by the Georgia Tech Research Institute (GTRI), were launched for NASA by SpaceX/Orbital Sciences to the International Space Station (ISS)."
Space X = Elon Musk = Solar City
The better question is should we be excited or concerned? Concerned in that SCTY may very well be developing its own 3d cell for solar panels. I have read that Musk's team has been looking into graphene also, guess time will tell. In any regards, it certainly does show the significance of the 3d cell.
