Resumen:

Colloidal quantum dots (QDs) are widely utilized for the development of light-emitting diodes (LEDs), photodetectors, and solar cells. Herein, PbS QDs were incorporated as interfacial modifiers between the perovskite layer and the hole-transporting material (HTM) in perovskite solar cells (PSCs). The results reveal that the use of PbS QDs leads to improved device thermal stability. This work proposes a method for analyzing the thermal stability of PSCs based on the impedance spectroscopy technique.
