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.en© 2016 American Chemical SocietyObservation of hot carriers existing in Ag₂S nanoparticles and its implication on solar cell applicationObservation of hot carriers existing in Ag(2)S nanoparticles and its implication on solar cell applicationJournal article003004970110.1021/acs.jpcc.6b026070003764175000112-s2.0-84971247572254424Kee, T.
