Halide perovskites are poised to realize the next generation of inexpensive yet high-performance optoelectronic devices, yet our understanding of key photophysical processes is still emerging. Here, I will cover our group's latest work on understanding photons in and photons out of these fascinating semiconductors, as well as the recombination processes occurring in between. I will cover our efforts on neat films as well as integrated perovskite/silicon tandem cells, perovskite/perovskite tandem cells and LEDs, covering both modelling and experimental imaging. I will cover important effects including light coupling between multi-layered stacks and non-radiative recombination processes. These efforts are pushing forward our understanding and leading to new strategies to optimise performance.
