Narrow-bandgap Sn-Pb mixed perovskite single crystals for high-performance near-infrared photodetectors

Zhizhen Chang et al.

Summary: Narrow-bandgap Sn-Pb mixed perovskite single crystals show great potential as photoactive materials for efficient and low-cost near-infrared (NIR) photodetectors. However, the phase separation issue during crystallization process leads to the degradation of optical and electronic properties. In this study, a low-temperature space-confined technique (LT-SCT) is proposed to reduce the crystallization velocities and create pure-phase (FASnI(3))(0.1)(MAPbI(3))(0.9) single crystals. These crystals exhibit excellent crystallinity, high hole mobility, and low surface trap density, enabling their application in self-powered NIR photodetectors with outstanding performance. The work contributes to the development of Sn-Pb mixed perovskite single crystals and offers a promising candidate for efficient and low-cost NIR photodetection.
