And the wires were not put up straight.

And that sparse array of wires has exactly the same light absorption and electricity-collection properties as the conventional silicon wafer cell."

And that bouncing around or multiple scattering in between the wires results in dramatically enhanced absorption,"

So all the wires stringing the distribution needs to be done on a more rapid basis and faster so we can get out to the consumer."
