Photoelectrochemical characterization of natural and synthetic molybdenum disulphide prepared by direct vapour transport technique have been carried out. The quality of the MoS 2 /electrolyte junction for photovoltatic applications was assessed examining the effect of varying light intensity on current voltage behaviour. For measurements at low intensity a broad light source was used. The ideality factor ( n ) was determined for these junctions by modelling the MoS 2 /electrolyte junction in terms of a Schottky barrier. The effect of intensity in the efficiency of the PEC solar cells has also been studied in detail. All the observations have been described and the implications have been discussed.
