The efficiency of perovskite photovoltaic cells is greatly impacted by the anomalous hysteresis effect. It is found that by applying a forward bias prior to testing, device efficiency (η p ) can be significantly improved. This bias poling effect can be stabilized at temperatures ≤250 K. As a result, hysteresis free operation of a planar perovskite photovoltaic cell is achieved at 170 K with η p of 19%.
