Observing Phase Transitions in a Halide Perovskite Using Temperature Dependent Photoluminescence Spectroscopy
FLS1000 Photoluminescence Spectrometer
Hybrid halide perovskite has recently emerged as a new class of low cost semiconductor for optoelectronic applications. They have received widespread attention as an absorber in photovoltaic cells, where they have achieved a remarkable increase in solar cell efficiency; from 9% in 2012 to 21% in 2017. Despite this high efficiency, further research into the elementary physics and stability of these materials is necessary. If importance is understanding how temperature affects the properties of the halide perovskite.
The FLS1000 Photoluminescence Spectrometer can be equipped with a range of cryostat accessories that enable the photoluminescence properties of a material to be studied over a temperature range of 2.3 K to 800 K.
In this application note the temperature dependence of the photoluminescence of methyl ammonium lead iodide perovskite is investigated using the FLS1000 with the liquid nitrogen cryostat accessory.
