Solar cells and light‐emitting diodes (LEDs) based on metal‐halide perovskites are transitioning from promising performers to direct competitors to well‐established technologies, with cost‐effectiveness as a strong advantage. Nanostructured perovskites have yielded record LEDs due to their higher versatility in the local management of charge carriers, which has enabled photoluminescence quantum yields (PLQYs) close to 100%. However, these perovskite nanostructures are yet to be fully exploited in other applications such as photovoltaics, where they can also present competitive advantages as they enable feasible routes to surpass the Shockley–Queisser limit by means of multiexciton generation or hot‐carrier extraction. Besides conventional applications, the extraordinary properties of these materials have the potential to unlock novel areas of research. Herein, the potential of perovskite nanostructures—with the focus on the widely developed nanoparticles—beyond classical thin‐film optoelectronics is analyzed, their limits of application are discussed, and their real possibilities are pondered.

钙钛矿纳米颗粒：在光伏和LED中的合成，性质和新应用
基于金属卤化物钙钛矿的太阳能电池和发光二极管（LED）正在从有前途的制造商过渡到直接竞争对手，再到成熟的技术，而成本效益是其强大的优势。由于纳米结构的钙钛矿在电荷载流子的局部管理中具有更高的通用性，因而产生了创纪录的LED，这使得光致发光量子产率（PLQY）接近100％。但是，这些钙钛矿纳米结构尚未在其他应用（例如光伏）中得到充分利用，它们还可以展现竞争优势，因为它们通过多激子产生或热载流子提取使可行的途径能够超越Shockley-Queisser极限。除了传统的应用 这些材料的非凡性能有可能开启新的研究领域。本文分析了钙钛矿纳米结构的潜力-着眼于广泛开发的纳米颗粒-除了经典的薄膜光电子学之外，还讨论了其应用范围，并探讨了其实际可能性。
