Perovskite and Organic Photovoltaics
Perovskite Photovoltaics
We are seeking to make perovskite solar cells a viable technology by focusing on its efficiency, stability, and scaling. Our research is currently focused in several areas, including 1) ultrahigh-efficiency and low-cost polycrystalline halide perovskite thin-film solar cells; 2) electronic energy level alignment at the carbon nanotube/organic metal halide perovskite interface; and 3) stable perovskite solar cells via chemical vapor deposition.
Organic Photovoltaics (OPV)
We develop and apply new absorber, contact, and barrier materials to advance the device performance and lifetime of organic solar cells. We have had an ongoing focus on developing new contact materials and device architectures. We continue to develop new electron/hole contact layers for increased lifetime and device performance, and tools for the intelligent design and synthesis of new absorber/donor materials. And we have developed a combinatorial degradation system that allows us to measure lifetime of thin-film devices under light, at different substrate temperatures, with or without filters or under different duty cycles.
