Stable Semiconductor Liquid Junction Cell with 9 Percent Solar-to-Electrical Conversion Efficiency

Abstract

The semiconductor liquid junction cell n -GaAs/0.8 M K 2 Se-0.1 M K 2 Se 2 -1 M 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.
