Abstract
We report on photovoltaic cells based on ternary PbS0.9Se0.1 quantum dots utilizing a heterojunction type device configuration. The best device shows an AM 1.5 power conversion efficiency of 4.25%. Furthermore, this ternary PbSxSe1−x quantum dot heterojunction device has a peak external quantum efficiency above 100% at 2.76 eV, approximately 2.7 × the bandgap energy. The ternary quantum dots combine the higher short circuit currents of the binary PbSe system with the higher open circuit voltages of the binary PbS system.
