Abstract

In this research, CH3NH3Pb1-xGexBr2xI3-2x perovskite films were prepared by a hot-casting method with 4 different GeBr2 concentrations (x = 0, 1/128, 2/128 and 3/128). The absorbance spectra of CH3NH3Pb1-xGexBr2xI3-2x at x = 2/128 has the highest intensity, and the energy band gap of all CH3NH3Pb1-xGexBr2xI3-2x films is approximately 1.60 eV. SEM images of all perovskite films represent the continuous and smooth perovskite film covering entire titanium dioxide (TiO2) surface. The CH3NH3Pb1-xGexBr2xI3-2x perovskite films were used as the light absorption layer in carbon-based hole – transport – layer – free (HTL) perovskite solar cells (PSCs). The performance of carbon-based HTL – free CH3NH3Pb1-xGexBr2xI3-2x PSCs in the first day was 3.97%, 3.37%, 2.96% and 2.54% for x = 0, 1/128, 2/128 and 3/128, respectively. The efficiency of the solar cell devices increased significantly to 5.33%, 4.33%, 5.90% and 5.96% for x = 0, 1/128, 2/128 and 3/128, respectively, after 1,000 hr.
