Abstract Solar cells employing lead halide perovskites as light absorbers have been one hot topic in recent years due to their amazing device performance and commercialization potential. Yet, there exist challenges on the way to their practical use, including long-term stability, and J-V hysteresis. Herein, we demonstrate an improved contact between perovskite and hole transporting layer (HTL) by using CdTe quantum dots, wherein the capping ligands on quantum dots are systematically investigated. The devices with the CdTe quantum-dot-in-perovskite solids interlayer achieve a high efficiency (~ 19.3%, averaged), and more importantly, a significantly reduced hysteresis, which is superior to devices with CdTe QDs capped by other ligands (PbI2, CH3NH3I, oleic acid). We attribute this superior device performance to the congeneric junction contact between perovskite and CdTe quantum-dot-in-perovskite layer. Furthermore, we reveal that the reduced hysteresis is partially contributed from faster hole extraction at the interface thanks to the high hole mobility in CdTe. These findings shed lights on the future design of quantum dots for perovskite optoelectronics in the perspective of ligand engineering. Highlights The CdTe-QD-in-perovskite solids were synthesized and used as modifier in perovskite solar cells. The CdTe-QD-in-perovskite solids modified solar cells exhibited high efficiency (averaged 19.3%) and negligible hysteresis. The influence of surface ligands of CdTe QDs on device performance are studied. Graphical abstract The J-V hysteresis is one notorious issue in perovskite solar cells. Interface engineering represents one possible solution to this problem. Herein, we incorporated CdTe quantum dots (QDs) between perovskite and hole transporting layer, trying to combine the merits of CdTe and perovskite materials to achieve high device performance. The influence of surface ligands of CdTe QDs on device performance were studied, and it is found that the cells with CdTe-QD-in-perovskite solids showed highest efficiency (averaged 19.3%) and alleviated hysteresis, compared with cells modified by CdTe with other ligands (oleic acid, PbI2, CH3NH3I). Further studied revealed that the reduced hysteresis is partially contributed from faster hole extraction at the interface. [DISPLAY OMISSION]
