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.

Application Note: Measuring Charge Carrier Lifetime in Halide Perovskite Using Time-Resolved Photoluminescence Spectroscopy

Halide perovskite photovoltaic cells have attracted tremendous attention over recent years due to the rapid rise achieved in solar cell efficiencies. In this application note time-resolved photoluminescence spectroscopy is shown to be a powerful tool for investigating and optimising the behaviour of halide perovskites through the measurement of charge carrier lifetimes.
