Metal halide perovskites and colloidal quantum dots (QDs) are two emerging class of photoactive materials that has been attracted considerable attention for next-generation high-performance solution-processed solar cells. In particular, the hybridization of these two materials has been recently demonstrated remarkable performance enhancement due to the complementary nature of the two constituents. In this review, we will highlight the recent progress of QDs and perovskite hybridization in solar cell applications. More specifically, the unique properties of monophase perovskite QDs will be summarised which are demonstrated by homogeneously hybridizing perovskite QDs into perovskite lattice. We also discuss the recent progress in heterogeneously hybridizing discrete colloidal QDs into perovskite layers which exhibit significant perovskite film stability enhancement as well as corresponding solar cell performance improvement. PbS QDs, other chalcogenides QDs, as well as emerging two-dimensional QDs, are further accounted through multiple methods, such as bilayer architectures, core-shell structures or blending multiple QDs into perovskite layers. In the end, an outlook perspective of this field has been proposed to point out several challenges and possible solutions.
