Characterization of low-frequency excess noise in perovskite-based photovoltaic cells

Abstract

We present experimental results on low-frequency noise characterizations of high-efficiency perovskite solar cells (PSCs). It is shown that annealing the device in dry oxygen results in significant enhancement in the power conversion efficiency of the device. Systematic investigations on the photothermal deflection spectroscopy and the low-frequency excess… (More)
