Detection of voltage pulse width effect on charge accumulation in PSCs using EFISHG measurement
( Elsevier , 2020 , Article)We report the effect of applied pulse width on charge accumulation in triple cation perovskite solar cells (PSCs) during the Electric Field Induced Second Harmonic Generation (EFISHG) measurements. The PSCs were prepared ... -
High Excitation Intensity Opens a New Trapping Channel in Organic-Inorganic Hybrid Perovskite Nanoparticles
( American Chemical Society , 2016 , Article)We investigated the excited-state dynamics of CH3NH3PbBr3 perovskite nanoparticles (NPs) and bulk crystals under various excitation intensity regimes using transient absorption spectroscopy. We confirmed the sub-band gap ... -
Inter-phase charge and energy transfer in Ruddlesden-Popper 2D perovskites: Critical role of the spacing cations
( Royal Society of Chemistry , 2018 , Article)Photo-generated charge carrier dynamics in Ruddlesden-Popper 2D perovskites with linear (n-BA) and branched (iso-BA) butylamine as spacing cations have been studied by using transient absorption and time-resolved ...
