Halide perovskites have opened up a new world of semiconductors that can be processed inexpensively by solution or vapour yet perform exceptionally well. These materials are realising new paradigms for solar cell manufacturing at high throughput, including lightweight, high power modules that could enable new applications in space, aerial communications and electric vehicles. Here, I will show new results in which we have vapour-deposited tunable halide perovskite absorbers, which we in turn use in high-performance tandem cells. I will show how sensitive the fabrication can be to processing conditions, and how to control such parameters to realise high performance including with passivation approaches. I will also show tests of halide perovskite devices for proton radiation hardness required for space applications, and characterise the devices on different length scales. The materials demonstrate extremely good resilience to proton radiation even at very high doses. However, I will also show their limitations when bombarded with electrons or X-rays.
