Application Note: Observing Phase Transitions in a Halide Perovskite Using Temperature Dependent Photoluminescence Spectroscopy

Perovskite photovoltaic cells are exposed to a wide range of temperatures and it is therefore important to understand the influence of temperature on the properties of the perovskite. In this application note, the FLS1000 spectrometer equipped with the liquid nitrogen cryostat accessory is used to determine the phase transition temperatures of MAPI perovskite.
