Tunable Semiconductors: Control over Carrier States and Excitations in Layered Hybrid Organic-Inorganic Perovskites
Chi Liu, William Huhn, Ke-Zhao Du +6
For a class of 2D hybrid organic-inorganic perovskite semiconductors based on -conjugated organic cations, we predict quantitatively how varying the organic and inorganic compon…
Carrier-Resolved Photo Hall Measurement in World-Record-Quality Perovskite and Kesterite Solar Absorbers
Oki Gunawan, Seong Ryul Pae, Douglas M. Bishop +8
Majority and minority carrier properties such as type, density and mobility represent fundamental yet difficult to access parameters governing semiconductor device performance, mos…
First-Principles Understanding of the Electronic Band Structure of Copper-Antimony Halide Perovskite: The Effect of Magnetic Ordering
Xiaoming Wang, Weiwei Meng, Zewen Xiao +3
We report the understanding of the electronic band structure of perovskite through first-principles density-functional theory calculations. We find that the mos…
Parity-Forbidden Transitions and Their Impacts on the Optical Absorption Properties of Lead-Free Metal Halide Perovskites and Double Perovskites
Weiwei Meng, Xiaoming Wang, Zewen Xiao +3
Using density-functional theory calculations, we analyze the optical absorption properties of lead (Pb)-free metal halide perovskites (ABX) and double perovskites (AB$^+…
Suns-V characteristics of high performance kesterite solar cells
Oki Gunawan, Tayfun Gokmen, David B. Mitzi
Low open circuit voltage () has been recognized as the number one problem in the current generation of CuZnSn(Se,S) (CZTSSe) solar cells. We report high light i…
