ABSTRACT
In this research, the TiO2 blocking layer of perovskite solar cells was made by two different methods, spincoating and spray pyrolysis. Optical properties of active layers were studied using diffused transmittance spectroscopy (DTS), and the photovoltaic properties of the solar cells such as Jsc , Voc , FF and the efficiency were measured. Due to the importance of transmission, the light from the blocking layer and the mesoporous TiO2 layer, the diffuse spectrum of these layers and also the importance of light absorption in the perovskite of the absorption spectra of this layer were investigated. Diffuse transmittance spectroscopy (DTS) was used to study the active layer from the view point of optics. Optical properties of the spin coating layer were not significantly different in the two methods, but after the deposited perovskite layer, it was observed that the optical properties of the perovskite layer in the range of visible light were different in both the spin coating and spray pyrolysis methods.
