摘要

Perovskite solar cells (PSCs) have undergone rapid progress and attractedconsiderable attention as a promising alternative to conventional photovoltaicsbut currently still face the challenges of Shockley-Queisser (SQ) limitand stability. Herein, the use of quantum dots (QDs) for the advancementof PSCs is focused on. The interactions between QDs and perovskite arediscussed in terms of energy and charge transfer. The effective strategies forperformance improvement of devices treated with QDs are interpreted fromthe point of view of surface modification (passivation and mixing), and microstructure(buffer function) and nanostructure (core/shell structure). In particular,possible routes to success in surpassing the SQ limit are summarizedin association with the corresponding mechanisms. Also, the mechanismsfor the enhancement of stability by QD treatment are analyzed, includingquantum confinement effect, crystallization, ion migration inhibition, hydrophobicityimprovement, passivation, and decomposition suppression. Inaddition, application of QDs to charge transporting layers is introduced andthe resultant changes in device performance and stability are pointed out.The insights gained from this review are very crucial for the further advancementof PSCs treated with QDs.
