[1903.09281] Low Frequency Carrier Kinetics in Perovskite

Abstract Hybrid organic inorganic halide perovskite solar cells have emerged as leading candidates for third generation photovoltaic technology. Despite the rapid improvement in power conversion efficiency (PCE) for perovskite solar cells in recent years, the low frequency carrier kinetics that underlie practical roadblocks such as hysteresis and degradation remain relatively poorly understood.
