There are two important factors, concentration and coating paste conditions of ZrO2, which is used as perovskite bottom layer to support its growth. In this paper, firstly, ZrO2 paste was synthesized and then with ratios 1:5 and 1:8, it was diluted in the ethanol. This mixture was used in the perovskite solar cell as porous bottom layer. Characterization of manufactured solar cell show that ZrO2 paste dilution rate has high impact on the perovskite solar cell and hence ratio 1:8 presents more efficiency. M3 ER -
