CuS nanoplates from ionic liquid precursors-Application in organic photovoltaic cells

摘要

Hexagonal p-type semiconductor CuS nanoplates were synthesized via a hot injection method from bis(trimethylsilyl) sulfide and the ionic liquid precursor bis(N-dodecylpyridinium) tetrachloridocuprate( II). The particles have a broad size distribution with diameters between 30 and 680 nm and well-developed crystal habits. The nanoplates were successfully incorporated into organic photovoltaic (OPV) cells as hole conduction materials. The power conversion efficiency of OPV cells fabricated with the nanoplates is 16% higher than that of a control device fabricated without the nanoplates. (C) 2018 Author(s).
