Highly efficient, financially feasible solar photovoltaic technology is crucial to the global transition from fossil fuels to renewable energy to mitigate climate change. Perovskite solar cells (PSCs) represent a promising next generation technology; they have already matched the efficiency of the current market-dominant silicon technology in just a decade of research. Widespread, viable commercial application of PSCs requires stable, scalable device structures to maintain efficiency over time. My goal is to enhance PSC stability and efficiency by studying charge carrier recombination and defect dynamics in the charge transport and active layers of PSCs through extensive device fabrication and subsequent spectroscopic characterization.
