Researchers compare the structural stability, electrical conductivity, and photo responsiveness of a lead-free tin halide perovskite CH3NH3SnI3 before and after high-pressure treatments up to 30 GPa. The pressure-driven phase transitions and evolution of associated electrical and optoelectronic properties have been characterized by in situ synchrotron X-ray diffraction (XRD), Raman spectroscopy, electrical resistance, and photocurrent measurements during two sequential compression and decompression cycles.
