Two-dimensional (2D) halide perovskites have recently emerged as a more stable and more versatile family of materials than three-dimensional (3D) perovskite solar cell absorbers. Although solar cells made with 2D perovskites have yet to improve their power conversion efficiencies to compete with 3D perovskite solar cells, their immense diversity offers great opportunities and avenues for research that will likely close the gap between these two. Further, 2D perovskites can have various roles within a solar cell, either as the primary light absorber, as a capping layer, passivating layer, or within a mixed 2D/3D perovskite solar cell absorber. In this Minireview, we will review the history of 2D perovskites in solar cells, the relevant properties of such materials, the different roles that they can play in a solar cell, as well as current trends and challenges.
二维（2D）卤化物钙钛矿最近已成为一类比三维（3D）钙钛矿太阳能电池吸收剂更稳定、用途更广泛的材料。尽管用二维钙钛矿制成的太阳能电池尚未提高其功率转换效率以与三维钙钛矿太阳能电池竞争，但其巨大的多样性为研究提供了巨大的机会和途径，这可能会缩小两者之间的差距。此外，二维钙钛矿在太阳能电池中可以扮演各种角色，既可以作为主要的光吸收剂，也可以作为覆盖层、钝化层，或者存在于混合的二维/三维钙钛矿太阳能电池吸收剂中。在这篇综述中，我们将回顾二维钙钛矿在太阳能电池中的发展历程、这类材料的相关特性、它们在太阳能电池中可以发挥的不同作用，以及当前的趋势和挑战。
