Abstract Herein, we correlate the chemical structure of the electrolyte with the performance of inverted Schottky quantum dot (QD) solar cells (SCs) having a structure of FTO/electrolyte/p-type PbS QDs/MoOx/Au-Ag. QDSCs of polyethyleneimine (PEI) or poly[(9,9-bis(3′-(N,N-dimethylamino)propyl)-2,7-fluorene)-alt-1,4-phenylene] (PFN) were fabricated for comparison. The open-circuit voltage (VOC) of QDSCs scaled with the workfunction of electrolyte – modified fluorine-doped tin oxide (FTO). Conjugated PFN electrolyte resulted in lower VOC but it boosted the current density (JSC) of QDSCs by lowering the interfacial potential barrier at FTO-PbS QDs contact.
