Hybrid organic–inorganic perovskites (HOIPs) are the emerging family of perovskite materials showing a diverse plethora of unique optoelectronic properties for promising energy applications for sustainable and green environment. These materials also show potential promise for fine tuning of structural, electronic, and optical properties under external stimuli like pressure, temperature, and electric field, which are having pertinent applications in the form of energy materials. This review portrays a critical take on the recent progress of pressure-induced structural, electronic, and optical properties tuning in hybrid perovskite materials under the influence of external pressure both from theoretical and experimental viewpoints. It also shows insight on the relevant and timely issues like encountering inaccessible structural phases through lattice distortion along with the Jahn–Teller distortions, evolution of bandgap and photoluminescence, Rashba-splitting, charge carrier mobility, and piezochromism under external hydrostatic pressure. Finally, explicit options on the future research scope including the enhanced properties in barocaloric materials under compression have been portrayed for HOIP materials family.
