Kyoto Institute of Technology in the news a few years back "New PV cell generates electricity from UV and IR light". "made by 'doping' a wide bandgap transparent composite semiconductor -- in this case, gallium nitride (GaN) -- with a 3d transition metal such as manganese. For the atomically impaired among us, the other metals of that family would be scandium, titanium, vanadium, chrome, iron, cobalt, nickel, copper, and zinc."
... and now "a leading distributor and integrator of solar systems in Japan", to supply up to 100 MW per year of CdTe (cadmium telluride) thin-film photovoltaic modules in Japan.
