Over the past decade, perovskite-based halide structures have been demonstrated as promising energy conversion devices through their application in solar cells. Currently, lead-based perovskite halides exhibit the highest energy conversion efficiency, but they are toxic and unstable by nature. The goal of this research is to study the feasibility of lead-free alternative options for the development of stacked cell structures for application in biomedical devices. This work involves the simulation, fabrication, processing, and characterization of fully inorganic perovskite based photoactive cells on flexible substrates to study the feasibility of devices for use as photoactive sensors in biomedical wearables. The stacked cells have an FTO(transparent conductive oxide layer), electron transport layer made of Electroactive Material Systems (BaTiO3, or ZnO) (blocking layer) and TiO2(mesoporous layer), perovskite layer, P3HT(hole transport layer), and Palladium(back contact layer). The results were analyzed for feasibility, degradation, and metrics identification for application in biomedical wearable and diagnostic devices.
