چکیده انگلیسی
In this work, perovskite solar cells (PSCs) were fabricated in the ambient air, with a scaffold layer composed of TiO2/ZrO2 double layer as the mesoscopic layer and carbon as the counter electrode. The effect of ZrO2 thin film thickness on the photovoltaic performances of PSCs was also studied in detail. Results showed that the photoelectric properties of as-prepared PSCs largely depend on the thin film thickness due to a series of factors, including surface roughness, charge transport resistance, and electron-hole recombination rate. The power conversion efficiency of PSCs increased from 8.37% to 11.33% by varying the thin film thickness from 75â¯nm to 305â¯nm, and the optimal power conversion efficiency was realized up to the 11.33% with a thin film thickness of 167â¯nm. This research demonstrates a promising route for the high-efficiency and low-cost photovoltaic technology.
