Perovskite solar cells have emerged out to be the most rapidly progressing solar cells in the history of photovoltaic research.¹ Undoubtedly, the perovskite absorber is the hero of the device structure, with excellent optical and electronic properties. But the different layers of the device have a significant impact on the overall performance of the solar cell. The study of these layers may provide answers to many existing problems, like low stability, reproducibility, low fill factor etc, associated with the device.^{2, 3} We have deposited the perovskite film over 3 different layers: NiOx, ITO and glass(SiO₂) by spin coating, and tried to investigate the influence of different under layers on the device performance, by correlating the optical and photovoltaic properties. This may be further useful to understand the phenomenon at the interfaces, which are directly influenced by the under layer of the perovskite film.
