In the area of photovoltaic, the silicon solar cell is the most popular and it has issues such as stability and scaling up cost. On the other hand, a dye-sensitized solar cell (DSSC) is one of the most promising candidates for a high-performance solar cell in the next generation, since it is fabricated by a simple manufacture process at relatively low cost. The focus of interest in this research paper is to mention the usage of maiden single and simple apparatus of spray pyrolysis thin film deposition to fabricate the electrode and counterelectrode for DSSC. It involves the novelties introduced in the instrumentation of the apparatus and the characterizations (x-ray diffraction, scanning electron microscope, and atomic force microscopy) of the prepared thin films for the fabricated DSSC. In this work, the pomegranate fruit dye is used to sensitize the nano-TiO2.
