PbS colloidal quantum dot (CQD)-sensitized inorganic–organic
heterojunction solar cells fabricated by using the PbS CQDs
co-capped by the oleic acid (OA) and 1-dodecanethiol (DT)
ligand showed better device stability with aging time under
ambient conditions without encapsulation. Furthermore, the
device performance is better than the cell fabricated from PbS
CQDs without DT ligand. The enhancement of performance in
OA and DT co-capped systems is investigated by impedance
spectroscopy. An upward displacement of the TiO2
conduction
band, with a consequent increase of Voc, results in the improved
performance when CQD with DT are employed. [-]
