Abstract

One-dimensional heterojunction devices are gaining attention because of improved carrier collection which results in improving the overall efficiency of a device. Herein, we report the synthesis of a CdS/p-Si nanowire (NW) hetero-junction device by wet-chemical methods and their potential application for electricity generation from atmospheric moisture. A single CdS/p-Si NWs hetero-junction based moisture enabled electricity generator (MEG) device exhibits a saturated maximum output voltage in the range of 250–300 mV and a saturation current of ∼0.2 μA in presence of humid conditions. This primitive module acts as a promising candidate for future energy generation devices constituting of individual units connected either through simple series or parallel connection to scale up high electrical power.
