Interestingly, when the optimal thickness of ZnO (33.5nm-thick) was deposited on the optimal thickness PCBM layer and the PCBM/ZnO bilayer was formed, the device showed remarkably enhanced device performance compared to the PCBM based device, resulting in the optimal PCBM/ZnO bilayer-based device reaching a PCE of 15.63 with VOC of 1.03V, JSC of 18.69mAcm−2, and FF of 79.95%, and the highest PCE of 16.39% was achieved.

In stark contrast, the CBM of the SnO2 ETM layer revealed an energy level 0.6eV lower than the perovskite which could lead to unfavorable charge accumulation at the interfaces as well as a loss in potential; however, the insertion of a C60 thin buffer layer facilitated the charge transfer between the SnO2 ETM and the perovskite.c displays the JV curve of the best performing device where the highest PCE recorded is ~18.8% along with a JSC of ~21.8 mAcm-2, a VOC of ~1.12V, and a FF of ~77%.

The VOC of a DSSC is determined by the difference between the Fermi level of the photoelectrode and the redox potential of the electrolyte Meanwhile, it has been reported that TiO2 coating on the SnO2 improved the cell performance by minimizing the problems of insufficient dye attachment and low VOC, the DSSC based on the TiCl4-treated WO3 nanorods exhibited the cell performance of JSC= 6.75 mA/cm2, VOC= 0.457 V, FF= 0.489, and η= 1.51%, all higher than the values of the DSSC based on WO3 nanorods.

In addition, the DSSCs assembled by MoSe2 CE achieved more remarkable photovoltaic performance (PCE=7.01%) for I3− reduction than standard Pt CE (PCE=6.38%), suggesting that MoSe2 nanoflowers could be a promising alternative for CE material in DSSCs.Dye-sensitized solar cells (DSSCs), with the high theoretical power conversion efficiency (PCE), low cost, multi-color transparent and environment-friendly characteristics, have aroused the concern of the world [].
