As the third technology of recent thin-movie sun cells, perovskite sun cells (PSCs) have attracted a whole lot interest for his or her splendid photovoltaic performance. Today, PSCs have suggested the very best photovoltaic conversion performance (PCE) of 25.5%, that's an encouraging value, very near the very best PCE of the maximum extensively used silicon-primarily based totally sun cells. However, pupils have determined that PSCs have troubles of being without problems decomposed below ultraviolet (UV) mild, poor stability, strength degree mismatch and intense hysteresis, which significantly limit their industrialization. As precise substances, quantum dots (QDs) have many splendid residences and were extensively utilized in PSCs to deal with the problems noted above. In this article, we describe the utility of numerous QDs as components in one of a kind layer of PSCs, as luminescent down-moving substances, and immediately as electron shipping layers (ETL), mild-soaking up layers and hollow shipping layers (HTL). The addition of QDs optimizes the strength degree association with inside the device, expands the variety of mild utilization, passivates defects at the floor of the perovskite movie and promotes electron and hollow shipping, ensuing in extensive upgrades in each PCE and stability. We summarize in element the function of QDs in PSCs, examine the angle and related problems of QDs in PSCs, and eventually provide our insights into the destiny route of improvement.
