Journal ArticleDOI
Rationalizing the light-induced phase separation of mixed halide organic-inorganic perovskites.
Sergiu Draguta,Onise Sharia,Seog Joon Yoon,Michael C. Brennan,Yurii V. Morozov,Joseph S. Manser,Prashant V. Kamat,William F. Schneider,Masaru Kuno +8 more
TL;DR: This model reveals that mixed halide perovskites can be stabilized against phase separation by deliberately engineering carrier diffusion lengths and injected carrier densities, and explains observed non-linear intensity dependencies, as well as self-limited growth of iodide-rich domains.
Journal ArticleDOI
Unusual energy storage and charge retention in Co-based metal–organic-frameworks
Deok Yeon Lee,Seog Joon Yoon,Nabeen K. Shrestha,Nabeen K. Shrestha,Soo-Hyoung Lee,Heejoon Ahn,Sung-Hwan Han +6 more
TL;DR: In this article, the cobalt-based metal-organic-frameworks (Co-MOF) was explored as a promising material for supercapacitors and a good pseudocapacitor behavior with the specific capacitance up to 206.76 F ǫ n−1.
Journal ArticleDOI
Tracking Iodide and Bromide Ion Segregation in Mixed Halide Lead Perovskites during Photoirradiation
Seog Joon Yoon,Sergiu Draguta,Joseph S. Manser,Onise Sharia,William F. Schneider,Masaru Kuno,Prashant V. Kamat +6 more
TL;DR: In this article, the phase separation of halide ion movement in mixed halide films is tracked through excited-state behavior using emission and transient absorption spectroscopy tools, and the time scale with which such separation occurs under laser irradiation (405 nm, 25 mW/cm2 to 1.7 W/cm 2) as well as dark recovery.
Journal ArticleDOI
Shift Happens. How Halide Ion Defects Influence Photoinduced Segregation in Mixed Halide Perovskites
TL;DR: In this article, the authors show that light-induced compositional segregation can be minimized in mixed halide perovskite films by using excess halide ions, and further reflect the importance of halide ion post-treatment of perovskiy films to improve their solar cell performance.
Journal ArticleDOI
Size-Dependent Photovoltaic Performance of CuInS2 Quantum Dot-Sensitized Solar Cells
TL;DR: In this article, the size-dependent solar cell performance for pyramid shaped CuInS2 QDs with diameters between 2.9 and 5.3 nm has been reported.
