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.

Efficient extraction of charge carriers is critical for the creation of high-efficiency solar cells. Photoluminescence is proportional to the number of charge carriers in the perovskite and therefore sensitive to charge transfer into adjacent layers which makes photoluminescence based techniques invaluable for investigating the performance of new extraction layers. In this application note, the extraction efficiency of a VACNT hole extraction layer is investigated using PL spectroscopy with an Edinburgh Instruments FLS1000 Photoluminescence Spectrometer.
