Abstract

Abstract: 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. Graphical abstract: Colloidal halide perovskite (CHP) nanocrystals (NCs)/quantum dots (QDs) have been quickly applied in photovoltaic devices, and great breakthroughs have been obtained due to their excellent optoelectronic properties. This review mainly discusses of CHP NCs/QDs from three aspects (physical properties, synthesis optimization and photovoltaic applications). A brief outlook is also presented, including the issues remained and the possible direction to deal with it.
