Development of perovskite solar cells by incorporating quantum dots

Quantum dot (QD) materials can provide tremendous benefits resulting from quantum confinement effect to photovoltaic devices such as perovskite solar cells (PSCs). In this review, attractive characteristics of QDs are introduced from the point of view of nano-size effect, multiple-exciton generation, phase stability and hysteresis suppression. The role of QDs in improving device performance is elucidated on the basis of band engineering, tunable surface chemistry and compositional engineering. In addition, the contribution of QDs to environmentfriendly devices is discussed. Finally, we discuss ongoing challenges and offer the perspectives on future advancement of PSCs with QDs.
