Fig. 3

a 3D AFM image shows the topography of an aluminium-doped zinc oxide (AZO) thin film with a doping concentration of 3% b 3D AFM image shows detailed depiction CuI with a NaI concentration of 0.075. c The depth profile of AZO samples that have been subjected to various electrochemical depositing durations. d The depth profile of CuI samples subjected to different numbers of dipping cycles. Collectively, these illustrations offer insightful details on the morphology and topographical nuances of the respective materials under varied conditions. e The transmission spectrum of the optimize AZO and CuI thin films that has the highest power factor. A photograph of the optimized AZO and CuI thin film against sky. f The optical bandgap energy of the highest power factor observed among AZO and CuI thin film samples.
