Description
Summary:Metal halide perovskites and colloidal quantum dots (QDs) are two emerging classes of photoactive materials that have attracted considerable attention for next-generation high-performance solution-processed solar cells. In particular, the hybridization of these two types of materials has 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, and are demonstrated by homogeneously hybridizing perovskite QDs into the perovskite lattice. We also discuss the recent progress in heterogeneously hybridizing discrete colloidal QDs into perovskite layers which results in significant enhancement in perovskite film stability as well as corresponding solar cell performance improvement. PbS QDs, other chalcogenide QDs, and emerging two-dimensional QDs are further accounted through multiple methods, such as constructing bilayer architectures and 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. Metal halide perovskites and colloidal quantum dots (QDs) are two emerging classes of photoactive materials that have attracted considerable attention for next-generation high-performance solution-processed solar cells.
