Some4 say he’s copied this:
“3D Solar Cells Boost Efficiency, Reduce SizeNew design uses “nano-Manhattan” carbon nanotube towers
Atlanta (April 11, 2007)
... The 3D design was described in the March 2007 issue of the journal JOM, published by The Minerals, Metals and Materials Society. The research has been sponsored by the Air Force Office of Scientific Research, the Air Force Research Laboratory, NewCyte Inc., and Intellectual Property Partners, LLC. A global patent application has been filed for the technology.
...The GTRI photovoltaic cells trap light between their tower structures, which are about 100 microns tall, 40 microns by 40 microns square, 10 microns apart—and built from arrays containing millions of vertically-aligned carbon nanotubes.
...The ability of the 3D cells to absorb virtually all of the light that strikes them could also enable improvements in the efficiency...”

maybe he’s just a good reader.
If he copied, or stole, (or “Biden-ed”) the idea, then the prize money committee should take some of the, uh, heat too.
