This project conducts a comparative study of optoelectronic properties in lead and lead-free monocrystalline and polycrystalline perovskites using near-field probes. It investigates how crystalline structures impact efficiency and stability in perovskite solar cells, a relatively unexplored area. This research promises new insights and practical applications for next-generation photovoltaic technology design and optimization.
