Lead-free halide perovskites, beyond solar cells and LEDs

In the last decade, halide perovskites have seen tremendous advancements, primarily in the field of solar cells and light-emitting diodes (LEDs). However, their remarkable optical and electronic properties are not only amenable for their use in solar cells and LEDs; as they can also be used for several other applications. While most research has focused on lead-based perovskites, their lead-free counterparts offer several potential advantages. Some of these advantages include reduced toxicity, improved stability, and a more diverse chemistry. Herein, we review some of the 'other' most notable applications of lead-free perovskites, including their use as photodetectors, photocatalysts, memristors, field-effect transistors, among others. We conclude by highlighting some of the pressing challenges and promising research avenues in the field.
