Under optimized conditions, the best PCE was increased from 12.8% to 16.2%, which should be attributed to the alleviated charge recombination due to the improved quality of perovskite films by suppressing the formation of CH3NH3PbCl3.Perovskite solar cells (Pero-SCs) have shown its potential for commercialization by continuous improvement of power conversion efficiency (PCE) and device stability [].

The significantly increased JSC of the CH3NH3Sn0.25Pb0.75I3 perovskite solar cells resulted in an average PCE of 8.45 ± 0.59% with a maximum PCE of 8.83% even though the VOC and FF were decreased.

The traditional method is to imbibe liquid electrolyte by dense PGE matrix, similar to strategy (i), the corresponding DSSC yields a η of 5.72% (Jsc=12.5mAcm−2, Voc=0.674mV, FF=67.9%).

Unfortunately, the experimental 0.9% efficiency of the novel copper redox couple was far away from that obtained with control iodine-based cells (η = 1.7%), being mainly negatively affected by the lower photocurrent (Jsc=2.4 and 3.8 mA cm–2, respectively).

The s-DSC device based on POZ7 showed the highest PCE of 6.24%, with a short-circuit photocurrent density (Jsc) of 9.86mA/cm2, an open-circuit photovoltage (Voc) of 0.87V and a fill factor (FF) of 72.8%.

The enhancement of the solar cell performance was ascribed to the g-C3N4 and Ag on the TiO2 surface, which could not only contribute additional electrons that increase the electron concentration in the photoanodes, but also suppress the backward recombination of electrons from TiO2 and the hole transporting layer.This work was supported by the National Natural Science Foundation of China (No.
