Radiative thermal escape in intermediate band solar cells
AIP Advances, 2011 To achieve high efficiency, the intermediate band (IB) solar cell must generate photocurrent from sub-bandgap photons at a voltage higher than that of a single contributing sub-bandgap photon.

Photovoltaic Effect in a III‐IV‐V Compound Semiconductor
Progress in Photovoltaics: Research and Applications, EarlyView.A large reduction of the GaAs band gap is obtained with incorporation of 6.5% Ge during epitaxy without introducing extended defects or composition inhomogeneity. Heterojunction solar cell devices were fabricated with 0.76‐V open circuit voltage and an internal quantum efficiency above 40% at energies below the bandgap of the GaAs emitter.
