  • Author: Stuart Thomson
Halide perovskite photovoltaic cells have attracted tremendous attention over recent years due to the rapid rise in solar cell efficiencies and their potential for providing high efficiency low cost solar power. Solar cell efficiencies have increased from 9% in 2012 to 21% in 2017 and are now competitive with traditional crystalline silicon cells. Despite this impressive rise in efficiency, the fundamental physics of these materials is not yet fully understood. In this application note time-resolved photoluminescence spectroscopy will be shown to be a powerful tool for investigating and optimising the behaviour of perovskite through the measurement of charge carrier lifetimes.
