Ultra High-Efficiency and Low-Cost Polycrystalline Halide Perovskite Thin-Film Solar Cells

Close

This project is developing high-efficiency single-junction perovskite solar cells, helping to gain an understanding of basic material and device properties related to halide perovskites, which will lead to the demonstration of ultra-high efficiency tandem thin-film devices. Researchers are using two complementary methods: solution processing and co-evaporation deposition. Theoretical modeling is being conducted to understand doping/defect physics for perovskites, while information learned on doping physics, defect chemistry, and device modeling will be made available to the photovoltaic community and will support solar manufacturers and start-ups looking for their next-generation photovoltaic products.
