Since it was first reported in 2014, colloidal halide perovskite (CHP) nanocrystals (NCs)/quantum dots (QDs) have been quickly applied in photovoltaic devices, and useful results have been obtained due to their excellent optoelectronic properties. In this review, we aim to summarize the progresses in this field up to now, and propose solutions to the development bottlenecks. Generally, we will first introduce crystal/electronic structures, optoelectronic properties and stabilities, and the synthesis methods of CHP NCs/QDs, followed by their applications in solar cell as active layer, interfacial layer, additive and energy transfer layer. Finally, we will briefly discuss the stability challenges for CHP NCs/QDs, and make a simple prospect for the possible directions of CHP NCs/QDs in future solar cell applications.

自2014年首次报道以来，胶态卤化钙钛矿（CHP）纳米晶体（NCs）/量子点（QDs）已迅速应用于光伏器件，并且由于其优异的光电性能而获得了有用的结果。在这篇综述中，我们旨在总结迄今为止该领域的进展，并提出解决发展瓶颈的解决方案。通常，我们将首先介绍晶体/电子结构，光电性能和稳定性以及CHP NCs / QDs的合成方法，然后介绍它们在太阳能电池中作为有源层，界面层，添加剂和能量转移层的应用。最后，我们将简要讨论CHP NCs / QD的稳定性挑战，并对CHP NCs / QDs在未来太阳能电池应用中的可能发展方向做出简单的展望。
