CH3NH3PbBr3 is not pyroelectric, excluding ferroelectric-enhanced photovoltaic performance
To experimentally (dis)prove ferroelectric effects on the properties of lead-halide perovskites and of solar cells, based on them, we used second-harmonic-generation spectroscopy and the periodic temperature change (Chynoweth) technique to detect the polar nature of methylammonium lead bromide (MAPb...
