Schottky-quantum dot photovoltaics for efficient infrared power conversion

Keith W. Johnston, Andras G. Pattantyus-Abraham, Jason P. Clifford, Stefan H. Myrskog, Dean D. MacNeil et al.
Planar Schottky photovoltaic devices were prepared from solution-processed PbS nanocrystal quantum dot films with aluminum and indium tin oxide contacts. These devices exhibited up to 4.2% infrared power conversion efficiency, which is a threefold improvement over previous results. Solar power conve ... [Appl. Phys.
