1 Introduction The difficulty in managing lead (Pb) toxicity and stability issues in Pb halide perovskites has steered an intense search for stable and lead-free perovskites that can yield comparable properties to their Pb-based counterparts for many optoelectronic applications.

1 Introduction Photodetectors, an essential optoelectronic device that converts optical signals to electrical signals, have attracted enormous research interest due to their wide range of applications in various fields such as digital imaging, optical communication, surveillance and sensing.[1-4] The growing demand for ultra-compact, cost-effective, low-power, lightweight and flexible devices has driven the exploration beyond traditional active materials (crystalline semiconductors such as...
