(A) IPCE spectra and (B) JV curve of the CQDSC. Inset of (A) shows the structure of the solar cell. (C) Variation of the FF and PCE of the CQDSC as a function of storage time. (D) EIS results of the CdS-sensitized solar cell and CQDSC. The symbols are experimental results, while the solid lines are fitted curves based on the equivalent circuit developed previously [26].
