Abstract: As one of the third-generation solar cells, colloidal quantum dot solar cells have attracted huge attentions owing to their simple preparation process and device flexibility. Notably, the surface passivation of the colloidal quantum dots for building the active layer has a critical impact on the device performances. This paper was aimed to briefly describe the recent research progress in surface passivation of the device-graded colloidal quantum dots and the effects of various ligands on device performances, with prospects of the future development trend.

Key words: colloidal quantum dots; ligand exchange; passivation; perovskite
