Perovskite-quantum dot hybrid solar cells: a multi-win strategy for high performance and stability
Abstract
Solution-processed solar cells have witnessed unparalleled progress in the past decade owing to their great potential in countering global warming and high competitiveness in light and flexible electronics. Perovskite solar cells (PSCs) and quantum dot (QD) solar cells are two representative emerging photovoltaic technologies that are highly complementary in terms of their optical and electrical properties. Herein, a critical review of the state-of-the-art hybrid perovskite-QD solar cells is presented with the aim of advancing their commercial applications. First, the working principles of hybrid perovskite-QD structures are discussed in detail with a focus on hybrid fundamentals. Subsequently, QD passivation with a perovskite matrix and perovskite passivation with QDs are outlined to highlight the great benefits of this hybrid strategy. An in-depth discussion is presented on the three main hybrid device structures, and corresponding worldwide research efforts to enhance the performance and stability of these promising hybrid solar cells. Lastly, the current challenges and future insights are presented to contribute toward further success in developing efficient and stable hybrid solar cells.
