Absence of ferroelectricity in methylammonium lead iodide perovskite

Ferroelectricity has been proposed as one of the potential origins of the observed hysteresis in photocurrent-voltage characteristics of perovskite based solar cells. Measurement of ferroelectric properties on perovskite solar cells is hindered by the presence of (in)organic charge transport layers....
