N2 - Perovskite solar cell (PSC), a type of solar cell including a perovskite-structured compound of a hybrid organic-inorganic lead as the light-harvesting active layer, is derived from the ABX3 crystal structure of the absorber materials where A and B are cation and X is an anion. The lead (Pb) in perovskite solar cells is not environmentally friendly. Therefore, it is necessary to substitute with another perovskite material such as barium titanate (BaTiO3). In this experiment, the various thickness and calcination temperatures of BaTiO3 thin film have been tested to determine their effect on structure and optical properties of BaTiO3. BaTiO3 thin film has been synthesized by the sol-gel spin coating method which was carried out by varying the spin coating rotation time (SCRT) for 30, 60, 90, and 120 s. Meanwhile, the calcination temperature was varied at 200, 400, and 600 °C. The sample without calcination (placed at room temperature) was set as a control. UV-Vis Spectrophotometer was used to quantitatively measure how much the samples of BaTiO3 thin film can absorb light, in order to identify its optical property. XRD and FTIR were used to analyze the crystal structure and the functional group bonds on the thin film, respectively. The obtained thickness resulted from various SCRT for 30, 60, 90, and 120 s, and treatments were 267.13, 222.24, 219.53, and 218.66 nm, respectively. The highest absorbance value was resulted in SCRT for 30 s with an energy gap and Urbach energy of 2.6 and 0.69 eV, respectively. Meanwhile, in the second condition, the obtained thicknesses were 755.91 nm from room temperature and 345.04, 267.14, and 246.30 nm from the various calcination at 200, 400, and 600 °C, respectively. The highest absorbance value was resulted in the sample with the calcination of 600 °C. Its band gap energy and Urbach energy were 2.31 and 0.64 eV, respectively. The result shows that BaTiO3 match for development of perovskite solar cells.
