Halide perovskite semiconductors are generating enormous exciting for light-harvesting and light-emission technologies. One of the keys steps to maximising optoelectronic performance is through eliminating non-radiative recombination mechanisms and hence maximising luminescence yields. Here, I will detail recent work in our group exploring how to best make each photon count in absorbers, emitters and full device stacks. I will present a combination of modelling and experimental results investigating how photons interact within and between layers in device stacks such as tandems, including photon recycling effects and light coupling between layers -- leading to key device design parameters. Furthermore, I will present results on both solar cells and light-emitting diodes (LEDs) exploring routes towards suppressing non-radiative recombination and therefore maximising performance.
