Lattice compression allows for systematic structural tuning without changing composition. Halide perovskites are a large and diverse family of solids, which have enormous potential for applications in energy capture, storage, and utilization. Notably, they have soft lattices and their photophysical and transport properties exhibit a large pressure response. In this Perspective, we highlight how pressure can alter their electronic landscapes, affect excited-state dynamics, and afford new structures not accessible through conventional syntheses. We further discuss how the insight we gain from high-pressure studies expands the scope of these versatile materials in current and future energy applications.
