(3-Aminopropyl)trimethoxysilane Surface Passivation Improves Perovskite Solar Cell Performance by Reducing Surface Recombination Velocity
Yangwei Shi, Esteban Rojas-Gatjens, Jian Wang +8
We demonstrate reduced surface recombination velocity (SRV) and enhanced power-conversion efficiency (PCE) in mixed-cation mixed-halide perovskite solar cells by using (3-aminoprop…
Extraction of instantaneous frequencies and amplitudes in nonstationary time-series data
Daniel E. Shea, Rajiv Giridharagopal, David S. Ginger +2
Time-series analysis is critical for a diversity of applications in science and engineering. By leveraging the strengths of modern gradient descent algorithms, the Fourier transfor…
Bismuth-doping Alters Structural Phase Transitions in Methylammonium Lead Tribromide Single Crystals
Erin Jedlicka, Jian Wang, Joshua Mutch +8
We study the effects of bismuth doping on the crystal structure and phase transitions in single crystals of the perovskite semiconductor methylammonium lead tribromide, MAPbBr3. By…
Imaging graphene moiré superlattices via scanning Kelvin probe microscopy
Junxi Yu, Rajiv Giridharagopal, Yuhao Li +5
Moiré superlattices in van der Waals heterostructures are gaining increasing attention because they offer new opportunities to tailor and explore unique electronic phenomena when s…
Sn4+ Precursor Enables 12.4% Efficient Kesterite Solar Cell from DMSO Solution with Open Circuit Voltage Deficit Below 0.30 V
Yuancai Gong, Yifan Zhang, Erin Jedlicka +12
The limiting factor preventing kesterite (CZTSSe) thin film solar cell performance further improvement is the large open-circuit voltage deficit (Voc,def) issue, which is 0.345V fo…
Noncontact Imaging of Ion Dynamics in Polymer Electrolytes with Time-Resolved Electrostatic Force Microscopy
Jeffrey S. Harrison, Dean A. Waldow, Phillip A. Cox +7
Ionic transport processes govern performance in many classic and emerging devices, ranging from battery storage to modern mixed-conduction electrochemical transistors. Here, we stu…
