Comparison of TiO2 Blocking Layers Prepared by Spray Coating and Spray Pyrolysis Of Perovskite Solar Cells

Abstract

In this study, the optical and photovoltaic properties of the active layer of PSCs prepared by rotary spraying and spray pyrolysis were studied and compared. Diffusion transmission spectroscopy (DTS) was used to study the optical properties of the active layer, and the photovoltaic performance and efficiency of JSC, VOC and FF solar cells were measured. Because of the importance of barrier layer and mesoporous TiO2 layer to transmission, the scattering spectra of these layers and the importance of light absorption spectra in perovskite are studied. Diffuse transmission spectrum of active layer is studied from optical point of view. Titanium and, finally, it can conclude that the bill of lading in spin coating and spray pyrolysis method does not block the sunlight reaches the perovskite absorbent and perovskite materials absorption rate, the bill of lading was built in the spin coating method, higher than the cells of the bill of lading is by spray pyrolysis, which is why the first condition of Jsc content is higher, this led to a higher efficiency than the second mode.
