|Abstract:||Silver sulfide, Ag, S, nanoparticle, NP, is a promising material for quantum-dot-based hot-carrier solar cell, yet the hot carrier dynamics of the material has not been thoroughly studied for this purpose. In this work, carrier cooling dynamics of Ag, S NP thin film were measured and analyzed using the transient absorption, TA, spectrometer. The NPs exhibit a relatively high carrier temperature and long carrier cooling time. This result was further verified by the carrier temperature extraction from steady-state photoluminescence, ssPL, spectrum. The long carrier cooling time in Ag, S NPs can potentially lead to efficiency of 33.6% demonstrating potential application for the high-efficiency hot-carrier solar cell.|
