Implication

This study demonstrates improved performance of photodetectors in Sn-halide perovskites through compositional engineering and graded heterojunctions, highlighting reduced defect densities.

Key Points

Superior near-infrared performance was achieved with external quantum efficiency of 63.4%, reducing defect densities in the process.
Improved film quality was confirmed by X-ray diffraction and photoluminescence techniques, indicating effective compositional engineering.
The use of C 60 as a passivation layer contributed to increased built-in potential and reduced trap density in the films.
Integrating compositional engineering with graded heterojunction formation, provides significant advances in Sn-halide perovskite photodetector technology.
