Abstract

AN alternative to conventional solid-state photovoltaic devices is the semiconductor/liquid junction. Liquid-junction cells not only offer the possibility of integrating energy conversion and storage functions1, but also may exhibit electrical properties that are fundamentally different from those in solid-state systems2. We have investigated the photovoltaic behaviour of n-InP/metal and n-InP/liquid junctions. We have found that the electrical properties of these semiconductor/liquid junctions are superior to those of n-InP/metal (Schottky barrier) systems, and that the current-voltage characteristics are a strong function of the electrochemical potential of the liquid phase. Liquid contacts thus provide a possibility for the construction of more efficient photovoltaic devices than those available at present from Schottky barriers.
