The semiconductor liquid junction cell n-GaAs/0.8M K2Se-0.1M K2Se2-1M KOH/C has been shown to attain 9 percent photovoltaic power conversion efficiency in sunlight. Accelerated tests under 3100°K light sources of several solar intensities indicate very low photocorrosion currents and high output stability.
