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.

在过去十年中，卤化物钙钛矿取得了巨大的进步，主要是在太阳能电池和发光二极管 (LED) 领域。然而，它们卓越的光学和电子特性不仅适用于太阳能电池和 LED；因为它们也可以用于其他几个应用程序。虽然大多数研究都集中在铅基钙钛矿上，但它们的无铅对应物提供了几个潜在的优势。其中一些优点包括毒性降低、稳定性提高和化学成分更加多样化。在此，我们回顾了无铅钙钛矿的一些“其他”最显着应用，包括它们用作光电探测器、光催化剂、忆阻器、场效应晶体管等。最后，我们强调了该领域的一些紧迫挑战和有希望的研究途径。
