Thanks to their better efficiency in a shorter period, Perovskite solar cells (PSC) have become a highly promising photovoltaic technology. However, the highest cost of hole transporting material and lower stability of perovskite handed their commercialisation. A dopant-free Hole-Transporting Material (HTM) offers protection to a perovskite layer from oxidation is one of the viable strategies. In this line of interest, Carbazole is a well-known electron-rich aromatic compound that has been widely used as a building block in organic electronic materials. This work falls into the theme of the investigation of the structural and optical properties of the thin films containing of carbazole unit substituted with diphenylamine deposited by physical vapor deposition. The obtained thin films were characterized by Atomic force microscopy, Transmittance and Photoluminescence measurements.The compounds demonstrated high Transparency in visible range with a Strong luminescence.
