Abstract

This article studied mesoporous TiO2 on the power conversion efficiency of perovskite solar cells by fabricating TiO2 paste instead of prefabricated TiO2, cutting the hole-transport layer, and using carbon instead of gold electrodes. The fabricated perovskite solar cells (PSCs) feature FTO glass/compact TiO2/mesoporous TiO2/CH3NH3PbI3/carbon electrodes. The mesoporous TiO2 layer was prepared from anatase TiO2 and dissolved in ethanol at the ratios of 2.63, 1.27, 0.65, and 0.32%, respectively. The best perovskite solar cell efficiency was obtained using a mesoporous TiO2 cell at a concentration of 1.27% with an open-circuit voltage (Voc) of 0.41 V, short-circuit current density (Jsc) of 3.48 mA/cm2, fill factor (FF) of 0.3, and power conversion efficiency (PCE) of 0.44%.
