ABSTRACT
A pair of lead-free chiral-polar perovskites of (S-MPz)6Bi3I21·6H2O and (R-MPz)6Bi3I21·6H2O have been acquired via the introduction of chiral cations. The distinctive self-powered X-ray detection with a considerable sensitivity of 5.2 μC Gyair−1 cm−2 is successfully achieved based on high-quality single crystals. This work highlights the potential of lead-free perovskites in self-powered X-ray detection.
